Hi I have COMPLEX PTSD and my psychologist is saying I have DID too.

I totally relate to your post, like another post I find myself choosing what to wear carefully - scared of the tradesman getting the wrong idea. It's as though I know on some logical level that I should be/feel safe but somewhere in my brain it just doesn't compute no matter what.

I find smells very triggering, so any lingering smells like aftershave etc freak me out - I usually have the Windows open to clear it, can be chilly. Then I feel like I can smell things when really they can't be there too.

Until I read a bit more about it I thought I was going mad. The hypervigellent side is exhausting.
You're not alone.
