It's so hard to handle this stuff. I Hope your panic attack ended. I have similar experiences but mostly am unable (too afraid something bad will happen if I do) to tell my therapist or pdoc. So no diagnosis.

Unless I'm manic/very mixed I think it is mostly PTSD stuff. For me it tends to be things I can find reasons for. When I'm up or mixed there is no reason for what I'm experiencing.

It's very difficult. As you know. I"m sorry I'm not much help; I woke up and saw this and wanted you to have an answer but I don't have a good one.
