Not My Circus, Not My Nervous System

It happens quickly.

A tense conversation. A last-minute change. Someone else’s problem arriving unannounced.

Before I even realize it, my body responds: tight chest, shallow breath, that subtle urgency to fix something that may never have been mine to fix.

For years, I mistook this for empathy. For being responsive, capable and helpful. I wasn’t simply noticing other people’s stress; I was absorbing it, carrying it and reacting as though it belonged to me. My nervous system was paying the price.

My body did not distinguish between a genuine emergency and an uncomfortable moment. Both produced the same internal alarm. The situation could belong entirely to someone else, yet my heart raced as though I had been assigned responsibility for solving it. Calm always seemed to be waiting somewhere beyond the resolution.

I remember pouring my heart into one particularly difficult conversation, hoping that if I found exactly the right words, I could create a different outcome. The response was dismissive. My body did what it had always done: tightened, braced and prepared to try harder.

But this time, something else appeared—a pause.

I noticed the tightness. I felt the familiar pull to chase, explain and repair. Then I asked myself a question that has since become a practice:

Is this mine?

The answer was no. Not the reaction. Not the dismissal. Not the emotional weight of what had happened.

That familiar phrase—Not my circus—suddenly felt incomplete. Even when I didn’t act, I could still carry the situation, replaying it and holding it in my body as if it were mine to resolve.

So I added four words:

Not my nervous system.

Boundaries are not just what we do. They are also about what we allow into our bodies. Someone can be upset. A situation can remain unresolved. A problem can be real without becoming an emergency in my body.

This did not change overnight. It became a series of ordinary pauses: a message I didn’t answer immediately; a conversation in which I listened without trying to fix; a moment when I noticed activation and chose not to follow it.

Pause. Notice what is happening in my body. Ask: Is this mine?

Sometimes the answer is yes. Often, it isn’t. When it isn’t, I practise letting the problem remain where it belongs.

Not cold. Not indifferent. Just clear.

The surprising part is that nothing falls apart when I slow down. Life continues. People have their reactions. Situations resolve—or they don’t. I can care without absorbing, be present without becoming overwhelmed, and stay engaged without becoming entangled.

These days, when I feel the urge to step in, fix or carry more than is mine, I return to the same reminder:

Not my circus. Not my nervous system.

And there is space again: a long exhale, a softer body and a little distance from what was never mine to carry.
