When OCD Disrupts the House Before Anyone Names It
When OCD first enters family life, it rarely arrives as a diagnosis. It appears as delay, tension, repetition and disruption. The morning routine buckles, rooms are avoided, questions are repeated, and ordinary life starts reorganising itself around something nobody has yet properly named.

What Are We Talking About When We Say Anxiety?

When Evidence Meets the Room: A Response to the BMJ Review on OCD
It describes what works. But not when it becomes possible.
In the clinic, ERP rarely fails because of effort. It fails when the thought is too close.
For some, there is enough distance to approach it. For others, there isn’t.
The issue is not motivation.
It is whether there is space in the mind for the work to begin.
