I thought could be PTSD too, but there are a lot of physical symptoms that you didn't describe so I didn't want to send you on a wild goose chase. But if it's part of your diagnosis...

I ignore my secondary diagnoses - treatment resistant depression, general anxiety, PTSD, yadda yadda yadda. What's the point when my primary diagnosis is all encompassing.
Until something pops one of them to the forefront and I have to spend all my energy dealing with it.

Good luck. Fingers crossed you find something that helps and this is temporary.
