I have had the sweating thing too. At the time that it was going on I'd lost a ton of weight as well. I had all kinds of medical tests and I suggest you do too. Have you had your thyroid tested?
Are you saying you only feel these things during periods of hypomania? Is it happening a lot? Or did it only happen one particular time that you were sweating and pacing, etc.? (when you were hypomanic?)
I am no expert but I really think your Dr. should know some of this stuff. I understand your paranoia. I have felt that too. As someone said, it really doesn't matter the exact dx, but some of your symptoms don't really seem to fit into a typical Bipolar category, IMO, and that is okay not to have a cookie cutter dx. I am not quite bipolar or depressive or sza either. I have experienced all of the above as far as symptoms of a dx. The important thing is to accept and learn to manage your symptoms with the help of a pdoc and therapist.
I hope it gets better for you.
