Hahahha, sounds like catch-22 if anyone's read it
Anyway, that was my anxiety fear. Because I always had depersonalization/derealization it really felt like I was going insane. I thought I was going schizophrenic. People have their triggers, some people think they are dying, some think they're having a heart attack, we think we're going crazy. As soon as I went on an antidepressant or took some ativan, this feeling would subside. Now I don't feel it at all anymore, so yes, it's a symptom of your anxiety. After a lot of research I've discovered that the depersonalization/derealization and fear of going crazy is much more a panic disorder symptom than a general anxiety symptom so although most of the same people visit both boards, you might have better luck on the "Panic Disorder" board.
