I agree with ultramar. Pdocs don't generally prescribe antidepressants to bipolar patients without a mood stabilizer and/or an antipsychotic to balance things out; otherwise s/he is apt to switch into mania. It's a good thing you're getting a different doctor; this one doesn't sound like he's got too much on the ball.

Frankly, the way he made (or didn't make) your diagnosis sounds like what medical people call a "wastebasket diagnosis", rather than a legitimate, well-thought-out assessment that says "OK, this looks like bipolar and smells like bipolar, but we haven't established a pattern of mood episodes yet that will tell us what 'flavor' you've got".

I started out with "question of depression" and Bipolar NOS. The depression dx went away after my pdoc observed me in the middle of a hypomanic episode, which changed my 'label' to BP 2 after several more such episodes, and may change again because my illness is still evolving (had a very nasty mixed episode that went on for almost six weeks). It's not at all unusual to have a BP diagnosis change multiple times, especially when you change pdocs.

For now, just try not to sweat the label too much, although your doctor should have given you a dx and explained what it meant. Keep us posted, OK?
