The emotion of disappointment is incredibly powerful, yet we rarely discuss it. It's an everyday emotion that doesn't get the headlines that anger, grief, or depression might get. But I believe it can be at the root of much emotional dysregulation. By understanding disappointment—what is happening in your body and brain, and the cycle it can create—you can better regulate your emotions, feel more contentment, and feel better about yourself. By the end of this article, you will understand disappointment and the cycle it creates. You will also walk away with practical tools about how to cut that cycle and prevent disappointment from becoming overwhelming. You might also learn to recognize disappointment as the root of a number of other emotions. Defining Disappointment Disappointment is sadness or displeasure when your expectations are not met. Basically, there is a gap between what you expected or hoped for, what you wanted, and what actually happens. It is that moment when you realize that reality is not matching your desires and sometimes your needs. When we think of that, we do not fully appreciate how painful it is. I am going to give you some information on the neurobiology so you will understand more about why it is so painful. I also want to talk about what happens when we are children and disappointed, and how the authority figures in our lives respond to us. This can create a pattern for whether we internalize or externalize disappointment, how resilient we are, and which pathway disappointment leads us down. Disappointment Never Shows Up Alone Disappointment almost never appears by itself. It usually comes with frustration and irritation, sometimes anger at ourselves or at somebody else, sadness and hurt. Very often we feel hurt when we are unable to get what we want or need. It also brings up shame and embarrassment. I think it is critically important to understand that disappointment is a very vulnerable emotion, primarily because it says, "I wanted that, and I did not get it." For some reason, saying that makes us feel very exposed, very unworthy. As most of you know, I worked as a psychotherapist for 20 years. In that work as well as in the online coaching programs that I have, I have noticed that people feel a lot of shame when they are asked to express out loud what they really want in life. I know this personally because it came up for me the very first time I was asked that question. It felt embarrassing to say it. It is very vulnerable to say, "I want this. I want it to look like that." I think it brings up feelings of: maybe I am ungrateful, maybe I should be grateful for what I already have. Who am I to think that I could have something like that? I should not be wanting it. When we get disappointed, we are essentially saying, "I cared about that thing and now I am feeling hurt, sad, or angry because I did not get it." So disappointment is a signal to us of what we want or of what we wanted. Understanding how vulnerable disappointment can make us feel can help us regulate that emotion because we can look into it more deeply and question some of our assumptions. The Cycle That Disappointment Creates As I go through this, you might want to jot down for yourself what the cycle is for you. I will be giving some examples, and it is helpful for you to begin to think through how this works for you. If you do not have anything to jot this down with right now, no problem—you can come back to it. Basically, disappointment starts with an event that does not match your expectations, desires, or wants. For some people, that mismatch will immediately create physical feelings: a sinking in the stomach, a feeling that the rug was pulled out from under you, a deflation. For some people, it might be more of a feeling of tension. The emotions that can accompany these physical feelings vary. If you feel a lot of tension, the emotion that can come up right away could be irritation, frustration, or anger. If you get that feeling that the rug is pulled out from under you, that could be shock. That feeling in the pit of your stomach could be simply disappointment, or it could be sadness. The reason I want you to be aware of your own cycle is that sometimes people are first aware of the physical feelings, but others are first aware of the emotional feelings. And a different group of people might be first aware of the negative thoughts that come up as soon as there is a mismatch between expectation and reality. The thoughts could be negative thinking about yourself, or it could be negative thinking about others. Your brain interprets the event, turning it into a story. And very often that story is driven by your negative core beliefs. If you have a negative core belief of "I am unworthy," the story will be, "Well, you did not deserve this. You are unworthy. You are not good enough." If your negative core belief is "I cannot count on others," well, this just reinforced that. I have a number of videos on negative core beliefs, and understanding which yours is and why it developed is very important. I am going to come back to that towards the end. In the meantime, I want you to know that I have a free PDF called " Transform Your Negative Core Belief. " It helps you understand which of those beliefs is truly at your core, and it gives you a handful of techniques to begin to rewire those beliefs. How the Cycle Spirals The way your brain interprets the mismatch is going to tie to those pre-existing negative beliefs. And all of that ties to early childhood experiences. This cycle is based on the Cognitive Behavioral Therapy (CBT) cycle. When an event happens and we interpret it, our thoughts That loop back and affect how we feel and how we behave. Similarly, all the feelings that came up with the disappointmet impact how we think and how we behave. The behaviors that very often come from disappointment can be avoidance or lashing out. Avoidance would be avoiding taking any risk because you do not want to feel disappointment again. This contributes to future problems, because taking reasonable risks is necessary to move you to where you want to be. And therefore there is more disappointment in the future. This cycle begins to wire our brain in a way that avoiding disappointment becomes the biggest thing we focus on, and our world can get more and more constricted. Lashing out: If one of your habitual patterns is anger, you might get angry and lash out at loved ones, which pushes them further away and makes the situation worse. Or you might go into a spiral of lashing out at yourself, and those negative core beliefs get more and more ingrained. This is not a good cycle. I want to help you understand it and shift it. The Neurobiology of Disappointment Deep in our brains, there is an ancient evolutionary part called the lateral habenula. You can think of this part of the brain as the "disappointment hub." This part of the brain activates when an anticipated reward does not materialize. That feel-good chemical you have heard about—dopamine—kicks in when we are anticipating a pleasure, when we are anticipating something good. Before an event, that chemical can kick in. But when that reward is not realized, the lateral habenula releases two other neurotransmitters. One is glutamate and the other is GABA. Glutamate is an excitatory chemical. It revs us up and amplifies the signals we are receiving. GABA is inhibitory. GABA slows things down and dampens signals. They have opposite effects, but they are released at the same time. The ratio of how much of each is released impacts how disappointed we feel. The ratio between these two chemicals is like the dimmer switch on how disappointed we feel. If we release a lot more glutamate compared to GABA, it is like turning that switch up—our disappointment increases. If we release more GABA, then we are lowering that dimmer switch. That is why sometimes we can handle disappointments without any problem, and other times they feel devastating. Given that dopamine floods our system when we are just anticipating something, when that mismatch happens, the dopamine levels can plummet, which gives us that sinking feeling and that real sadness. As I am saying this, I am thinking sometimes people feel a little sad even when an event meets their expectations because the dopamine does not always continue to be released—just a little aside there. The Long-Term Effects of Repeated Disappointment What happens if we regularly experience a lot of disappointment and we have a strong reaction to that disappointment, which would be contributed to by that negative cycle we talked about? When you have a lot of that, your brain can learn to stop anticipating good things. If wanting something leads to pain, I better not want anything at all. This causes a rewiring in the brain where that dopamine cycle dampens, and we neurologically withdraw from motivation and anticipation. The good news is we can rewire the brain. Our brain learns and changes throughout our whole lives. With the right guidance and the right effort, you can begin to rewire that pattern. I do not want you to lose hope here. How Childhood Shapes Our Response to Disappointment As we explore this, I want to encourage you to look at the patterns from your childhood as if it is a fact-finding mission, not a fault-finding mission, because it is much more productive to really look at this as "Why did I develop these patterns?" so you can have empathy towards yourself without immediately going to blame. Let us think about a 2-year-old. I am sure many of you have spent time with two-year-olds. If you think about it, those 2-year-old tantrums are almost all about disappointment. They are almost all about that 2-year-old wanting something or wanting to do something that they either cannot get or they are not allowed to do. It is disappointment mixed with frustration, and it is an unbelievably powerful emotion. It is so powerful that the 2-year-old ends up on the floor screaming and banging their fists. This is a challenging stage for parents. I do not know any parent who does this stage perfectly, but some do it adequately and others maybe do not. But it is a universal stage. It is so instinctual, so basic to us. When you think about it this way, you can understand how common this is and how much power this emotion that we rarely discuss has. Common Parental Responses to Disappointment Many parents will try to calm the child, which is good. But often we do that by brushing away the disappointment. "Oh, do not be so disappointed. We will do such and such tomorrow." This can be frustrating for a parent because the child could be hugely upset—you promise to take them to the park and there is a thunderstorm happening. You cannot take them to the park. But the child does not understand that. They do not have any perspective. The fact that a parent tries to bring in perspective makes sense. But if this pattern of dismissing the child's upset continues, that child will learn, "This is an emotion I am not supposed to have." The child will not feel seen or heard. Worse, sometimes a parent might totally withdraw from the situation, which is very threatening to a toddler. Toddlers and young children are completely dependent on their caregivers. If the caregiver withdraws physically or emotionally, that is very threatening to that child's survival emotionally. Other parents might get angry and lash out. Thinking through how your disappointments were handled can help you understand how you feel about that emotion right now. I also want to talk about parents who panic when their child is disappointed. They might get anxious and try to jump in and fix it right away. They might even give in to whatever it was—take the kid outside in the storm, whatever it was. The parent might panic and try to get the kid not to be so upset. But that also teaches us that this is an anxiety-provoking emotion and that if this emotion is scary to my caregiver, wow, that is really scary. Comment below if this makes sense and if you know the pattern of how you were responded to when you were disappointed. This completely natural state happens a lot, very frequently, and you learn from how you are responded to. Becoming a Disappointment As you got a little older, you might have begun to be aware of your parents' disappointments. If disappointment was such a horrible, scary emotion when you had it, you immediately will think it is a horrible, scary emotion for them to have. They might respond that way too. You may develop a feeling of "I am a disappointment to my caregivers." It could also be "I am a disappointment to my teachers, to my siblings," and that eventually will lead to an internalized negative belief: "I am a disappointment." I think you can see why this article is as long as it is. This is a very complex emotion that impacts us significantly. Even later in life, as we grow up and move away from our parents, other people have a hard time with our disappointment and we have a hard time with theirs. When somebody is disappointed, we all jump in right away. We want to make them feel better. We want to say, "Oh, it is not so bad," or "Oh, you will get it next time." We want to whitewash the pain. If you find yourself in that situation doing that to somebody else who is disappointed, maybe just slow down, take a moment and say, "Wow, I totally understand why you are disappointed. That is really hard." Let them sit with it. If you practice doing that for others—and maybe you already can do that, I am not judging here—but if you can do it for others, you can then begin to do that for yourself, which is going to lead me into the practical tools I want to talk about. Three Practical Tools for Managing Disappointment #1: Accept and Acknowledge the Emotion This relates to what I just said. Accept and acknowledge the emotion you are having. Acknowledge that you are disappointed. Let yourself take a minute to feel it without having to fix it. I know this always sounds counterintuitive to people, but our emotions ebb and flow. They do not ever stay exactly the same. Generally when we push away or try to whitewash or cover up an emotion, it gets stronger. Whereas if we just sit with it and feel it and think, "Okay, where do I feel this in my body? What am I thinking? What thoughts is this bringing me to? What if I just sit here with the physical feelings and let them be for a second?" With this awareness and acknowledgement, bring in some diaphragmatic breathing. Let your body, let your physiology know that you are okay. This may not feel good, it might hurt, you do not like it, but you are okay. Your body can begin to respond to it with more calm, with more of that GABA, and you can contribute to that with your own emotional regulation tools. #2: Become Aware of Your Cycle Become intimately aware of that cycle. What you feel in your body, what emotions you are feeling, what thinking you are having, and your behaviors as well—how those all interact with each other. Once you have a true awareness of your cycle, you can figure out where is the easiest spot to intervene. In general, we cannot directly change our feelings other than by simply sitting with them. We cannot do something to make them change. What we can do is question our thinking, begin to think about things differently, or change the behaviors. #3: Pick a Behavior That Breaks the Pattern Pick a behavior that does not go with your typical downward spiral and practice engaging in that behavior. Behavior is the most dramatic way to begin to change the wiring in our brains. A challenge for you could be to pick something that you have been avoiding because you are afraid of that disappointment. It could be something small. It does not have to be a major thing. Just go for it. Do it. See what happens. Approach it as if it is a scientific experiment. It could be: - Applying for an opportunity you have been avoiding - Simply texting a friend that you have been afraid to text because you are worried that they will not respond the way you want them to - Sharing an idea that you have with somebody when you have been avoiding that because you are worried that they will not like the idea These could be small things, but pick one and go for it. Moving Forward As I wrap up here, my other videos on emotional regulation skills will be really helpful for this. Just thinking about disappointment as one of those core emotions that can set you down a negative cycle, you can maybe begin to think about it differently so that you bring in those emotional regulation tools simply for disappointment. As one of my friends said, that is an everyday emotion. We feel that all the time. I really hope this was helpful. Make sure to check out that PDF—I also have a free webinar called "Rewire Your Brain," and it goes a little more into how our behaviors can help to rewire some of these patterns we have developed. Make sure you are subscribed so you will see the next video on this topic, which is going to expand on these tools. Let me know what you think. Let me know the questions you have and I will see you next week.
