Up until the point where you wrote about your doctor, I was thinking "Uhuh, uhuh, mania uhuh, depression, uhuh.. what's the problem?".

You sure sound bipolar to me, textbook example. I would get a new doctor ASAP, and get a psychiatrist and tell him/her about all of that and be HONEST. Then I'd ask for the SCID-II test, and as long as you allow yourself to answer honestly - you will get a straight answer.
