Why Do I Overreact? Understanding Emotional Responses

I always feel like I overreact. Especially because my reactions don’t always stay inside. Sometimes they show up in public—in parking lots, grocery store lines, or traffic when I’m already tired and just want to be home.

When I’m out running errands, I’m on a mission. I want to get in and get out. I’ve always been that way. For me, I become easily overwhelmed by my environment.

If I’m out shopping, I get sensory overload. The lights, the sounds, the smells, all can make me uncomfortable. Waiting in lines makes things louder in my mind, and standing still for too long feels utterly unbearable. My patience runs thin and it often disappears faster than I can catch it.

I’m known to start mumbling things under my breath. Complaining, sighing too loudly, letting my frustration leak out in ways I don’t realize until I’m already in the thick of it.

Recently, I was at the market, frustrated after waiting so long in the 10 items or less line. I began expressing my emotions and frustrations out loud, letting my anger show. The guy in front of me asked me if I was okay. I immediately blushed, turned away, and nearly cried, feeling a meltdown coming on. Then he asked if I wanted to go before him. That did it for me. I was so embarrassed by my actions: my complaining, my impatience, my foolishness. Once I got back to my car, I let it all out and scream-cried from embarrassment.

And then someone notices. “Are you okay?” That question makes my stomach drop, my cheeks turn red, and my tears rise to the surface.

Because suddenly I’m aware of myself—my tone, my face, my body. I feel exposed. Like I’ve embarrassed myself without meaning to. The irritation spikes, but underneath it is shame. I get angry, not just at the situation, but at myself for being seen like this.

I’ll watch other people standing so calmly in line just scrolling through their phones, waiting without any visible frustration. But there I am, standing there tapping my foot, thinking why things aren’t moving along faster or why I always have bad luck choosing the wrong line to be in. I take their quiet as proof that I should calm down, be less of a complainer, be less dramatic and stop being someone who makes too much out of nothing.

I don’t choose to act this way. It’s an automatic reaction. My body will respond before my brain has time to catch up. By the time I realize what’s happening it’s already over.

The aftermath of it all hits me with a wave of emotion. I’ll replay everything I said, wishing I had kept it in, feeling guilty for bringing my emotions into public spaces. I tell myself that I made things worse. That I overreacted. That I should have handled it better.

Even when I’m socializing, my mind is loud. I overthink and mentally react to everything and then judge myself for it. On the outside, I seem fine. On the inside, I feel ridiculous.

My thoughts tell me that I’m too much, even when I’m being quiet. They tell me that I can’t trust my own reactions. That my feelings are something to be embarrassed by.

Lately, I’ve been wondering if what I call “overreacting” is really just overload. A nervous system that reaches its limit quickly. A body that reacts before it has the chance to explain itself. I realized that when I overreact, I’m really just feeling things deeply, and intensely.

Maybe the hardest part isn’t the meltdown. Maybe it’s how harsh I am with myself once it’s quiet again.

I don’t know how to change this yet. But I’m trying to stop calling myself dramatic. I’m trying to name what’s really happening — overwhelm, exhaustion, and a need for relief.

Have you ever felt your emotions spill out in public, leaving you embarrassed afterward? How do you cope when your reactions feel bigger than you expected?
