I certainly know how you feel I too have doubted that I was BP. Being BP2 and not having the overt manias that others write about also has caused me to doubt my diagnosis too. I wrote a thread about it a few months ago and hamster did the same recently too. Three things have reduced that doubt 1 like you a really trust my pdoc who has no doubt that I'm BP. 2 a friend who knew me before medication confirmed for me that I used to be out of control. And 3, recently I've had a few hypomanic symptoms following the birth of my son.

I think there are a few things that contribute to the doubt that we commonly face: we have selective memories and often forget what things were really like especially during an episode; we don't want it to be true and we don't like taking medications all the time; and there are usually other things that contribute to our illness that are unrelated to the disorder.

I would suggest that you talk with your new pdoc about your symptoms, your history and your past and see what they say. Let them know what medications have worked and what ones have not - to a certain extent this is more important than knowing the exact diagnosis and try therapy to work on the anxiety - if you do have an anxiety disorder not a mood disorder then therapy may be able to resolve it or at least improve it.

Good luck with your journey and I hope it all works out well for you.
Good luck also with your relocation. I moved cities a couple of years ago and the first year in my new city was quite difficult.
