Why You Can't Stop Thinking About Your Mistakes (And What It's Really About)

If you've spent the last three days replaying one email, one comment in a meeting, or one decision that didn't land the way you wanted, you already know how disproportionate it can feel. The mistake itself might have been small. The reaction to it doesn't feel small at all. If you've typed some version of "why can't I stop thinking about my mistakes" into a search bar at 1am, this is for you.

In my therapy room, this is one of the most common patterns I see in high achievers and founders. Clients will often open a session with their achievements: the deal that closed, the decision that paid off, what someone said about their work. The mistakes come later, if they come at all. That's usually because achievement is how they learned to be loved: through good behaviour, high performance, and not needing anyone. Mistakes threaten that whole system. A mistake at work doesn't just threaten a job. It threatens a sense of self.

Why One Mistake Can Feel Like a Threat

The way you manage a mistake as an adult tends to come from a much younger part of you, the part that learned what happened at home when you got something wrong. Were you punished? Shamed? Was the mistake ignored, with only achievements ever recognised? Many high achievers still feel, somewhere underneath the job title, like a nine-year-old being told off, unable to tolerate the simple feeling of I got that wrong.

That inability to tolerate being wrong is what turns an ordinary mistake into a threat. It tends to show up as one of five responses: fight, flight, freeze, fawn, or flop. Sometimes it shows up in your body before it shows up in what you do: a stomach that won't settle, a headache that arrives right on cue, before your mind has caught up with what it's actually reacting to.

Here's what each of those five responses tends to sound like, and what's usually sitting underneath it.

Blaming Others: "My Colleague Is Incompetent"

This is one of the clearest projections I see in the therapy room. A fear about yourself that you're not ready to look at directly, aimed instead at someone else. It becomes easier to complain about a colleague's incompetence, a client's slow reply, or how everyone else made the job harder, than to look at your own part in what happened. Blame isn't really about the other person. It's about protecting the same thing every time: the sense that you're still someone who gets it right. This shows up most in workplaces with a culture of high performance, where a mistake isn't really allowed and your worth is conditional on output.

Avoidance: "Let's Not Talk About It"

Avoidance shows up in the unopened email, the conversation you keep meaning to have, the thing you don't look at because looking at it means looking at the less high-achieving parts of yourself, the parts you've quietly decided are unlovable. If you grew up with conditional love, getting something wrong doesn't just feel bad. It feels like a risk to being loved, by others and by yourself. Avoidance isn't laziness. It's usually a nervous system deciding that not looking is safer than looking.

Freezing: "I Don't Even Know Where to Start"

Freezing looks like a complete standstill: the inbox stays open, but you can't write the first line. From the outside it can look like procrastination. From the inside it's closer to paralysis, because every option feels like it could confirm the very thing you're afraid of, that you're not as capable as everyone thinks. High achievers are often the last to recognise this pattern in themselves, because it doesn't match their usual competence. That mismatch, I'm normally so on top of things, can make it harder to admit to. There's a physical cost here too: when the mind shuts down, the body often stays braced with nowhere to send the stress response, which is often where stomach issues and tension headaches come from.

People-Pleasing: "Is Everything Okay?"

This one hides well because it looks like graciousness: the over-apologising for something small, the rushing to reassure someone before they've even said they're upset, taking on extra work to make sure no one's annoyed with you. It's rooted in a sense that love or respect might be withdrawn the moment the cracks show, so you manage everyone else's feelings first. It's often mistaken for being easygoing or a team player, which is exactly why it rarely gets questioned.

Self-Criticism: "Maybe I'm Just Not Good Enough"

This response turns inward completely: self-doubt, catastrophising, replaying the same five minutes of a meeting on loop for a week. Underneath it is usually a lack of self-compassion, so thoughts land like bullets instead of information you could actually use. Left unchecked, it rarely stays contained at work. It bleeds into relationships and a general sense of not being good enough, until the gym, socialising, and rest are often the first things to get neglected. If this ever tips into a sense of real worthlessness, that's worth taking seriously rather than passing over.

How to Actually Move On From a Mistake

None of these five patterns are character flaws. They're what an overwhelmed nervous system does, running quietly underneath a job title, a leadership role, or a reputation for being the reliable one. The useful part isn't judging which one you default to. It's getting curious about it, before it hardens into a story you have to explain in hindsight.

Next time it happens, three questions are worth sitting with: What would it mean to fail at this? What does it say about me if I did? And who would still love me anyway?

Growth is holding both answers at once: I can fail, and I am still worthy of love. Not one proving the other. Not one cancelling the other out. Two separate truths that were never actually linked, no matter how long they've felt like the same sentence.

If this resonated, I write about this kind of thing every week on Grounded, my Substack newsletter: groundedbyrachel.substack.com.
