I'm pretty sure I have GAD (mainly hypochondria), particularly because I've "had" about 20 fatal diseases in the past few months.

Anyway, I've been noticing lately that I get a lot of twitches in my legs/eye/chest when I'm not in a particularly anxious mood. Of course, these twitches make me very anxious, which just makes them worse.

Is it normal to have episodes physical symptoms without experiencing mental symptoms?
