lotusflames! Sorry you are having such a rough go of it right now...
I have problems with lightening-speed rage. Much less often since proper medication, fortunately. More often comes serious irritability, which I've been having quite a bit of lately. Suppose it's better than rages(!), but still... Might well be a mood shift. I've been pondering the same question, lotusflames.

Be sure to let your doctor know about the spiders. It must be very disconcerting.
