Hi, PurpleFlyingMonkeys.

From this and your other recent posts, it sounds to me, and I'm no expert, but it sounds like you're having depersonalization/derealization symptoms. I've had similar experiences to nearly all the ones you've mentioned, so I know how scary it can be. ((safe hugs))

The further I've gotten in learning how to manage my mood disorder (I have MDD) and developing PTSD coping skills, it happens less but I find relationships trigger it more than anything else. I don't know if there's a way to completely stop it from happening but when it does, the thing that helps me the most is to avoid panic. (Easier said than done, I know.) If you can catch yourself and do a quick coping exercise before you start to panic, it should be more managable, and if you're vigilant about maintaining focus, (again, easier said than done,) hopefully it will happen less and less over time.

If you have a t, definitely bring it up with them. I'm sure they know a lot more about it than I do. Hope these symptoms let up soon. You deserve a break.
