When the Small Stuff Feels Way Too Big
You get a vague message—“Let’s talk when you have a sec”—and suddenly you're on edge, re-reading emails you sent last week and mentally preparing for the worst. If you’re like me, your next question is “why do I overreact to small things like this”.
Been there. More times than I’d like to admit. I started digging into this when I realized my emotional reactions were exhausting me. Not every day, but enough to make me stop and go: Wait, is this really about the email… or something else? Spoiler: It was something else.
What you and I are actually dealing with is something called hypervigilance—our nervous system’s way of saying, “we’ve seen this movie before, and it didn’t end well.” From what I’ve learned, this is often rooted in past stress or trauma and is a common driver of emotional reactivity. According to the Cleveland Clinic, hypervigilance keeps your nervous system in constant survival mode, making calm responses harder to access.
Emotional regulation is what helps shift that survival response—so your nervous system doesn’t have to treat every moment like a crisis. Understanding what emotional regulation is (and isn't) is the first step toward shifting that pattern.
It’s Not the Moment—It’s the History Behind It
You’re not overreacting because the moment is that intense. You’re overreacting because your nervous system has been there before. A harmless comment, a neutral tone, a slight delay—your brain isn’t just responding to what’s happening now. It’s responding to what it remembers feeling in similar moments, especially ones where you didn’t feel safe, seen, or in control.
When those memories live in your body unprocessed, they show up as big reactions to small triggers. It’s not that you’re too emotional—it’s that you’re emotionally overloaded. The more you can spot your emotional triggers before they take over, the more space you create to respond instead of react.
Your Nervous System Is Driving, Not Your Mind
This is something I really didn’t get until I read The Body Keeps the Score by Dr. Bessel van der Kolk. (Highly recommend, by the way.)
Dr. Bessel van der Kolk explains how past emotional wounds—especially those stored in the body—can shape how we respond in everyday life. If your body feels unsafe, your logic doesn’t stand a chance. You might freeze during a routine meeting or over-apologize when no one’s upset with you.
When you’re triggered, your logical brain takes a back seat and your nervous system jumps behind the wheel. Fight, flight, freeze, fawn, flop—your body reacts before your thoughts even show up. It’s not overthinking—it’s overstimulation.
You may think you’re being irrational—but it’s your nervous system calling the shots. When something small sets you off, you’re likely in a stress response: fight, flight, freeze, fawn, or even flop. These reactions happen in your body long before your brain has time to make sense of the situation.
Asking Yourself Why Do I Overreact to Small Things? It Might Be Because You’re Taking It Personally
Ever heard a totally neutral comment—“You seem tired” or “Just wondering…”—and felt your whole body tense?
Yeah. Same.
That’s not you being oversensitive. Apparently, that’s your brain connecting the dots back to old pain. When you're emotionally flooded, your mind fills in the blanks with fear, not facts. You interpret neutral as negative, and boom—reactivity.
It’s not fun, but it’s common. Here are 6 signs you might be taking things too personally if this one hits home.
Sensitivity Isn’t the Problem—Reactivity Is
Here’s the difference I wish I’d known sooner:
Sensitivity is feeling deeply.
Reactivity is what happens when those feelings take the wheel.
And reactivity? It’s not a flaw—it’s a survival response. Something you likely learned during stressful times when it wasn’t safe to process in the moment.

Check In Before You Spiral Out
That split second between feeling something and doing something? That’s your magic moment.
When I started noticing that space—even just pausing to take one deep breath—I stopped reacting like the sky was falling every time something felt off.
This doesn’t mean perfection. It means awareness. That’s emotional regulation in action.
Emotional Reactivity Can Quietly Drain You
If you’re always on edge, always recovering from some internal chaos, you’re not just stressed—you’re stretched thin. Overreacting to everything takes a toll on your body, your energy, and your sense of self.
According to the National Institute of Mental Health, chronic stress hits nearly every system in your body. Mood. Focus. Sleep. All of it. It adds up.
You don’t need to push through—you need tools.
Tools That Help You Respond Instead of React
You don’t need a full personality reboot. You just need a few go-to strategies that help create space between the trigger and the reaction.
Here’s what helped me:
Breathwork (even 3 deep breaths works)
Grounding techniques (feet on the floor, name 5 things you see)
Labeling emotions (“I feel anxious” is more useful than spiraling silently)

It’s Not Overreacting—It’s Unprocessed Protection
I used to feel ashamed of my reactions—like they meant I was weak or difficult. But honestly? They were just signs I needed support. And now that I know that, I can respond with more compassion, less chaos.
You’re not “overreacting”—you’re reacting from somewhere that still needs healing. And that’s okay. Because healing is possible. And it doesn’t start with fixing everything. It starts with noticing.
