It's amazing how the fear will sneak up and bite you in the a$$ when you least expect it. I also will have panic attacks/nightmares/crying spells seemingly out of nowhere.
Yoga really helps me. How long have you been on the drugs? They take a while to kick in (well, the Ativan shouldn't, that should be instantaneous, but the Celexa takes a while). I also like reading things on Buddhism. But it's amazing how some focused breathing (like in yoga) can help with the anxiety.
Also try to find a self soothing activity. I know it sounds odd, but I really like to color (yes, like in a coloring book, like a 4 year old). It's deeply relaxing to me. Find something that make you feel like that (knitting? couponing? pinterest? gardening?).
I still am having a hard time with the anxiety and the anger, and it seems to rear its ugly head when I least expect it, but those are some tools that help me.
