Anxiety & Overthinking

Why Do I Overthink Everything?

By Carla Costa · Published 11 August 2026 · 7 min read

It's midnight, the decision was small, and it's still being replayed for the fifth time — what was said, what should have been said instead, what it might have meant. Overthinking rarely announces itself as a problem in the moment. It feels like being thorough, like taking something seriously. It's only afterward, exhausted and no closer to resolution, that it's clear how little the loop actually accomplished.

What overthinking is actually trying to do

Underneath it, overthinking is usually an attempt at safety. The mind treats uncertainty as a kind of threat, and repeated analysis as a way of reducing it — as if enough turning-over will eventually produce a version of certainty. It rarely does. Most overthought decisions don't get clearer with the tenth pass; they just get more tiring, and the anxious feeling that started the loop tends to still be there at the end of it, only now paired with fatigue.

This is closely tied to anxiety more broadly — the same nervous system state that produces physical tension and restlessness produces racing, repetitive thought when it's turned inward on a decision or interaction instead.

Why it targets some things and not others

Overthinking rarely spreads evenly across every part of life. It tends to cluster around whatever feels highest-stakes to the person doing it — social interactions, work performance, decisions that feel irreversible. Perfectionism is a common companion here: the same drive that sets a high bar also tends to treat any uncertainty about meeting it as something requiring more analysis, not less.

Why willpower rarely switches it off

"Just stop thinking about it" tends to fail for the same reason most direct instructions to a racing mind fail — it's not a conscious choice being made repeatedly, it's closer to a groove the mind keeps sliding back into, especially at night, or in any quiet moment without enough else to hold attention. Fighting a groove head-on tends to deepen it; the effort of trying not to think about something usually keeps that thing prominently in mind.

The loop isn't solved by more force. It settles when the underlying alarm — the thing convincing the mind that vigilance is still required — gets addressed directly.

What tends to help

  • Naming the loop as it's happening, rather than following it — a small shift from being inside the thought to noticing it from slightly outside.
  • Giving the mind a genuine stopping point, such as writing the thought down to return to at a set time, rather than trying to resolve it indefinitely in real time.
  • Working with the underlying alarm state directly, rather than only the thoughts it produces — which is where approaches like hypnotherapy tend to be more useful than reasoning with the thoughts themselves.

Hypnotherapy works with this at the level of the nervous system's alert state, rather than trying to out-argue each individual thought — similar in principle to how it approaches other automatic, trigger-driven patterns. More on how that process works here.
