I agree with everyone above. My first dx was bipolar 2 because I never described any past manic episodes with the psychiatrist who originally dxd me. Only depression and anxiety. He dxd me bipolar 2 when he himself saw me hypomanic. I refused the Lamictal he wanted to prescribe and didn't return to him for about a year when the you know what hit the fan. In the hospital the first time, I had bipolar NOS. Then later hospitalizations I was so manic (some with psychosis), exhibiting every symptom in the book, that I became unequivocally bipolar 1. I've had many full blown manias since then.

You may never reach full blown mania. Or maybe you will. But I imagine your illness course will provide additional information about your "flavor" of the illness.
