It's hard to say whether you're bipolar from what you have said, and also because I'm not a doctor. But there are plenty of people who function very well despite bipolar. I work full time as well (although I'm on leave right now). Lots of people have made it through school and things like that. It doesn't mean you're not bipolar. If you're not happy with your pdoc, maybe think about trying to get in to see someone else for a second opinion.
