OCD is a loop, not a personality trait. An unwanted thought, image, or urge shows up and brings intense doubt or distress (the obsession).

Answering the question relieves the anxiety for a moment, which teaches the brain that the question needed answering. The doubt returns stronger and more often. Support that helps sounds like naming the loop with warmth instead of settling it — and agreeing together, in advance, to answer less.

Start by noticing what you've taken on: checking for them, avoiding certain words, buying extra soap, doing the routine so the evening goes smoothly.
