I doubted for a long time time that I was bipolar even after I was diagnosed and put on mood stabilizers. I was still pretty sure it was "just" depression because I didn't think I had ever had a manic or even hypomanic episode. Looking way back before I was diagnosed with anything I can see some times that I may have been manic. After my most recent episode that I'm still trying to recover from, I no longer have any doubt. I was in a full blown mania; I'm officially bipolar. Listen to your docs, who may have a clearer perspective than you. I agree with the advice some of the others here have given - try putting things down on paper and see how it looks in black and white. Best of luck to you either way.
