Cognitive Defusion: Help for Anxiety

Barbara Heffernan • November 27, 2024

Cognitive FUSION is the main problem underlying ANXIETY.

Cognitive fusion is always a component of anxiety.


Understanding what cognitive fusion is and what cognitive diffusion is can truly help you recover from anxiety. 


If you are able to “defuse” from your thoughts, your anxiety will drop dramatically. 


This blog will help you understand what cognitive fusion is and what cognitive diffusion is and how they relate to anxiety. And then I'm also going to give you three techniques that you can put into place fairly quickly to help yourself recover from anxiety. 


Cognitive fusion is when we are totally engulfed by our thoughts. We believe them. We physically experience them. We have a very hard time separating from them. We aren't able to see “this is me” and “those are my thoughts.”

When diffused from our thoughts, we see ourselves as separate from our thoughts. We know there are different thoughts we could think. We can analyze our thoughts. [I do have a whole
video explaining cognitive diffusion which I will link here].

What happens with anxiety is we begin to think about a problem and we just go into the whole story. We project out into the future all the bad things that could happen. Our mind is racing with the problem and our body is generating fight flight freeze chemicals.

We are NOT in our “planning brain” or in our “solution-focused brain.”

In order to come up with solutions, particularly creative solutions, we need our full brain online. When we go into that anxious mode, it's mainly our amygdala, the fight, flight, freeze response, that is driving everything.


The fusion with anxiety is the reason we believe what our anxiety is telling us. 


Your anxiety convinces you that you have to worry. 


It is almost as if your anxiety wants to justify its existence. 


I was a psychotherapist for 20 years working with people with anxiety and trauma, and one of the things that got in the way of people recovering from anxiety was a belief that “I have to worry about this.”


People would say, “I have this health problem, how do I not worry about it? Of course, I should be worrying about it.”


“I have this problem with my job, this problem with housing, this problem with a relative, etc..." 


And yes, these are real problems. Sorting them through and figuring them out is helpful, if there's something you can do about it. For this, you need your planning brain, not your anxiety.

But the anxiety is telling you, “You need me, you need me, you have to do this.”

That is part of the fusion. 


So cognitive diffusion as it relates to anxiety is separating from those anxious thoughts. You might still have the anxious thoughts, but you can look at them with more perspective, from a bit of a distance. You can separate the thoughts from your need to respond physically, so you can calm yourself physically while thinking about a difficult problem. 


Now, I know this is much easier said than done. It can be very hard to do. But there are tools that can really help, if you do them regularly. You can be more of an observer of your thoughts rather than drowning in them, rather than letting them control you.

If you diffuse from an anxious thought and separate from it, you won't spiral down with it. It won’t lead you from one worry to the next and the next. 


Three Exercises to Help Diffuse From Anxiety

Alright, let's talk about some techniques to do this.  I'm going to give you three very practical exercises you can do. 


The Balloon Technique

I'm going to start with the example of taking care of my four-and-a-half-year-old granddaughter, which I was doing a couple of weeks ago. She had a nightmare in the middle of the night. Her parents were away and she's not used to them being away so it wasn't too much of a surprise that she might have a nightmare. She woke me up in the middle of the night and I went to her room with her. We laid down and I tried different things to help her fall back to sleep: singing a song, telling a story, deep breathing.


But she wanted to talk about whether her dream would come true. She didn't really want to tell me the dream, but her anxiety was, “How do I know a dream won't come true?” So I addressed this directly, saying that dreams don't come true. They're just something our brains make up while we sleep. But that is hard to explain to a four and a half year old. 


Eventually I suggested that she imagine a balloon and imagine putting her nightmare into the balloon. I said she could pick the color of the balloon to help her visualize it. And I told her we were going to then let the balloon go and watch it fly away with the nightmare. She picked the color blue. 


I had her imagine putting the nightmare and the worries about that nightmare into that balloon and letting it float up to the sky. After that, she did finally fall asleep. 


This “balloon technique” is basically the same as watching your thoughts fly away, or float down a river, or drive by in a car. It is “taking the thoughts out of you,” putting them somewhere and letting them go. 


This is a tool of cognitive diffusion. It's separating from the thoughts enough to actually visualize whatever you're worried about leaving you. So that's tool number one. 


The Goofy Voice Technique

So, after the balloon visualization, my granddaughter slept fine the rest of the night. However, she brought the nightmare up the next day, again with the worry about whether or not it might come true. 


After she had asked me this many, many times, and I had tried many different ways to help her stop worrying about it, I finally said, “Tell me the story of your dream in a goofy voice.” She looked at me as if she couldn't even imagine that. So I said, “How about I tell you the story of your dream in a goofy voice?” After she said, “okay,” I made my voice really high and squeaky, and I told her the dream in a very goofy voice. She hesitantly smiled and laughed a little bit.


Then we did it again in a different goofy voice.


And then we did it again in a different goofy voice. And then I said, “Let's change the ending of the dream. Let's tell the story with a different ending.”


So in our goofy voices, we told a story that ended well.

She moved on to other topics (phew!).


The goofy voice technique is also a cognitive diffusion technique, which was developed as part of Acceptance and Commitment Therapy. 


It’s been proven that the goofy voice technique can help with separating from thoughts (cognitive diffusion).

I also want to give you a corollary to this technique. When I was working with people as a psychotherapist, I would have them create a character on their shoulder that represented their anxiety. And then when they had anxious thoughts, they could put them in the character that was on their shoulder. [This is explained more in a video I have on
Generalized Anxiety Disorder].


So, as you can see, that's an extra step of diffusion because you are putting the thoughts almost into another being. You could imagine any character to represent your anxiety: the road runner, the Tasmanian devil, etc. 


You can begin to see that the anxiety is trying to accomplish something, but it is not doing it in an effective way. 


Thoughts for Sale Technique


Alright, so we are going to move on to technique number three, which is a little bit more sophisticated. This third technique, “thoughts for sale”, is also from Acceptance and Commitment Therapy.

The technique is to imagine that you are at a yard sale and different thoughts or different types of thoughts are on the different tables, and you get to pick which one you go with. So you can take your rumination thoughts and put them at one table, and you can take your catastrophizing thoughts and put them at another table. And you could put being mindfully in the moment on a third table. And perhaps there could be a planning table where you can purchase the thoughts that go with planning.

Which thoughts do your choose?

Implementing These Techniques

Now, I know a lot of this is way easier said than done, and these techniques do take time and practice.


It can be very helpful to have somebody outside of yourself who can help guide you through it, a therapist or a coach. 


I don't do therapy anymore, but I do have an online program called
Roadmap to Joy and Authentic Confidence. It’s a six month program because it takes time to change how you think. The program is geared to help lower anxiety and negative self-talk, improve your mindfulness and develop healthy boundaries. All of these things help make life more joyful.  I put all of that together in a comprehensive six month program with a workbook, prerecorded videos, and emails to remind you to move on to the next section. The link is here, check it out, you might find it super helpful.

And, finally, let me know which of these three techniques you plan to try!

Understanding the Fawn Response The Fawn response is a behavior developed in childhood, often connected to complex trauma. It could even be little "t" traumas on an ongoing basis, where as a child, you learned to subjugate yourself to the caregiver in order to stay in relationship and survive. This becomes a deeply ingrained survival behavior which can become habitual. As you grow up, it gets applied to all situations. This blog will go through nine components required for healing. - The first three focus on internal work - The next three are more practical, action-oriented techniques - The last three address deeper psychological work Internal Work (Components 1-3) # 1. Recognize that fawning developed because it was necessary at the time Understand that fawning was a survival strategy, and it might have been the very best choice available to you. It may also have been, in many ways, the only choice. Even today as adults, there are situations where choosing a fawning-type behavior might actually be the best choice. This is important to understand because we don't want to eliminate this response entirely—we want to get to the point where it's not an automatic go-to reaction. Instead, we want to reach a place where you can consciously think, "I'm choosing to do this right now." Acknowledging that this developed as a survival strategy helps prepare you for the next two components. [ For more information on what the fawn response is and why it developed, read this blog] # 2. Begin to acknowledge and validate your own feelings If you grew up in an environment where you learned to fawn, my guess is that not only were your caregivers not paying attention to your feelings, but you also had to subjugate your own feelings to the point where you weren't aware of what you were feeling. As an adult, it's necessary to begin recognizing and identifying your emotions: "I'm feeling angry" or "sad" or "frustrated" or "irritated." Begin to acknowledge and even verbalize what you're feeling. The simple act of labeling your emotion calms down your fight-flight-freeze response and increases activity in the areas of the brain that help you solve problems. There is research that shows this happening via fMRIs! # 3. Practice self-compassion Understanding why this behavior developed can help you practice self-compassion. Changing these behaviors is hard and takes time. If you find yourself automatically fawning and later yelling at yourself, try not to do that—you're basically re-traumatizing yourself for a behavior you learned for survival. Instead, try noting it with self-compassion: "Interesting, I fell into that pattern again." And then connect this to the next step by adding, "I fell into that pattern again because of this situation." Observe with compassion rather than judgment. Practical Tools (Components 4-6) # 4. Identify situations that trigger fawning behavior Notice which situations trigger your fawning behavior. As you review these situations, see if there are patterns similar to those you experienced as a child. They may reflect situations that were emotionally or physically dangerous, or that created a rift between you and your caregivers. Identifying these situations helps you understand what patterns became embedded in your emotional brain. As you observe these patterns, bring in self-compassion and that observer mindset. This approach is much more productive than criticizing yourself. As you identify these patterns, you can connect them to current situations: "This situation at work with a difficult authority figure is recreating this childhood pattern for me." You are bringing in your frontal lobe to analyze the emotional reaction, which helps you realize, "That was threatening to my very existence when I was a child, but it is not threatening to my existence right now." This recognition is crucial because automatic fawning behaviors come from a need to survive immediate danger. The uncertainty of longer-term consequences (like losing a job) might be problematic, but it's not an immediate survival threat. Differentiating between then and now helps calm your fawn response. # 5. Keep a journal to track people-pleasing behaviors Keep a journal for 30 days. Journal on this question: "Did I say or do something today to please someone else that was at my own expense?" As you review the events of each day, you might realize, "I didn't do it this situation, but I did do it in those five situations." Again, maintain self-compassion with no judgment—just observe and be aware this will take time. This question gets at the heart of the issue: What did you do today that ignored your own values or needs in order to stay in relationship with someone else, avoid criticism, or prevent rejection? Verbalizing this through an audio journal or writing it down utilizes different parts of your brain that help you comprehensively understand what's happening. # 6. Practice emotional regulation tools daily Implement diaphragmatic breathing, grounding exercises, or any techniques that calm your physiology. Practice these regularly, not just in the middle of triggering events. You can weave these practices throughout your day. Set an alarm for three different times during the day, and when it goes off, simply take three deep diaphragmatic breaths. No one needs to know you're doing it—you can do it anywhere, and it's free. While it might not feel immediately helpful, you're stimulating a different part of your nervous system that helps you realize, "In this situation, it would not be life-threatening if the relationship were severed. I'm not in a situation where my immediate survival is at stake." When you feel safe enough, your normal breathing pattern will naturally be diaphragmatic. It's all a feedback loop—a body-based technique that communicates to the rest of your brain. The fawn response is differentiated from the fight-flight-freeze response. Sometimes they're grouped together, but I think it's more useful to separate them (I'll cover this topic in the future if you're interested—let me know in the comments). The fawn response uses different parts of the nervous system and brain because it's largely about staying in connection with others. That said, knowing whether your underlying response is fight, flight, or freeze beneath the fawn behavior can be helpful. People who fawn typically have either a flight response (wanting to run away) or a freeze response. Fighters rarely develop the fawn response. I recently created videos and blogs about calming the fight-flight-freeze response that might be useful for you. Deeper Work (Components 7-9) # 7. Recognize your negative core beliefs Identify what beliefs developed when you were young that led you to fawn, and what beliefs developed as a result of fawning. A common belief for people who fawn is "my needs don't matter," or even " I don't matter." Other common beliefs include "I'm not good enough," or "I'm powerless." A general feeling of being in danger is also common. Identifying these negative core beliefs and beginning to use tools to rewire them is extremely helpful. [I have a free PDF that helps you identify these beliefs and learn tools to rewire them. You can find it by clicking here ]. # 8. Learn to recognize and separate from limiting thoughts Notice when your behavior is driven by your negative core beliefs, whether you're fawning or not. You might operate from these beliefs almost all the time, even when not actively people-pleasing. Begin to separate yourself from these thoughts. Not all of our thoughts are true. Not all of our beliefs are true. We can "diffuse" from our thoughts by using our observer mind: "Interesting, I'm thinking that again, but I know it isn't necessarily true." A helpful technique is to "practice as if." If you feel like your needs don't matter, pretend that they do matter. Ask yourself, "What would I do right now if my needs mattered?" You can practice this approach in small ways. Your behavior, even if it is coming from a place of pretense, will actually begin to rewire these beliefs. # 9. Establish healthy boundaries I've placed this component last because establishing healthy boundaries isn't simply about saying "no." (Sometimes saying no is a healthy boundary, but sometimes it's not—and boundaries encompass much more than that). Healthy boundaries require a deep understanding of yourself and your values, and an understanding of where you end and others begin. To truly understand healthy boundaries requires deep inner work. The other components we've discussed, particularly emotional regulation, are prerequisites for establishing boundaries. Until you develop a certain level of emotional regulation, it's nearly impossible to implement healthy boundaries. When your amygdala is firing with the fight-flight-freeze response, your response is automatic and happening too quickly for your rational brain to intervene. Your rational mind might know "I should be saying no right now" or "I should leave this conversation," but the panic response has already set in, and your brain is focused solely on keeping the relationship intact and staying safe by avoiding conflict. This is why healthy boundaries aren't just about learning more information. You've probably read extensively about boundaries and have cognitive awareness of what healthy boundaries might look like. Then you get frustrated when you can't implement them because no one talks about the fact that boundary-setting starts with emotional regulation. Healthy boundaries also require healing negative core beliefs and knowing (even if you don't yet feel it ) that you can be safe without maintaining a toxic relationship, you can be safe even when there's conflict. A Structured Approach to Healing In my boundary program , I've designed an approach which walks you through the CORE components of healing and establishing helthy boundaries. The program helps you: develop the emotional regulation you need to begin to set boundaries identify and heal the negative core beliefs that are driving unhealthy boundaries learn assertive communication (as opposed to passive or aggressive) understand how to set boundaries and consequences and begin to do so! (For more info on the boundary program, click here) Learning assertive communication is essential because people with fawn patterns often use passive communication. Assertive communication represents the middle ground between passive and aggressive communication. It embodies the principle "I'm okay, you're okay." Many people who fawn misinterpret assertive communication as aggressive, and since they don't want to be like their aggressive abuser, they default to passive communication. But there is a healthy middle ground. As always, I'd love to hear your thoughts and questions—please comment below. I truly hope this is helpful, and I'll see you next week.
