You are not on a lot of meds, and your doses are in the mid-range. I think there's a lot more that can and should be done in the area of your anxiety. You don't necessarily need a benzo---if you can avoid using them, it's usually best because they are VERY addictive. (I've been on benzos for so many years now that I'll probably never come off.)

But there are some anti-depressants that can help prevent anxiety, and at low dosages they're less apt to flip you into mania. (That's why I'm also on a sub-subtherapeutic dose of Celexa, even though ADs in larger amounts make me manic. It's worth the small risk to keep the anxiety to a minimum.) Talk to your new pdoc about it and see what s/he thinks. Good luck.
