It's possible that you don't have bipolar, but from what you've described, you seem to have some sort of mood disorder. It may only be cyclothymia (or however it's spelled), but without the use of drugs or intense amounts of caffeine, it sounds like hypomania. For all I know you could be ADHD or have a thyroid problem, but I'm not a doctor. If you don't have down swings into depression for days on end, it might not be bipolar at all. I hope you'll keep your appointment and be honest with the doc so you can get a better idea of what you're dealing with and how best to treat it.
