You might check out a book called "why am I still depressed" and the accompanying website psycheducation.org. It looks specifically at bipolar II and gives specific suggestions on how to talk to your doctor about what you believe to be your diagnosis. I found his info very helpful.

The name of the diagnosis matters less than the meds that they give you. Have they been giving you mood stabilizers or just regular antidepressants? I had a pdoc that said I was maybe BP II and treated me medically like I was BP II, but on my paperwork just listed depression. I thought that was silly, but at least I got the right meds.

Best,
