Vickie makes a very good point. Diagnoses are really just for Docs and insurance companies.
Who cares what lable the use. As long as they know your symptoms they can treat the symptoms.
Not every bipolar has the same symptoms as one another and that goes for ever diagnosis.
My advice--Just be open and honest and write stuff down for the appointment so you don't forget anything.

GOOD LUCK!! Be sure and let us know how it goes!!!
