I had known that I had mental health "issues" for a long time, problems with highs and lows, and I sometimes suspected that I might have had cyclothymia because full-blown bipolar seemed too severe and scary. Then I did some research and discovered that you don't have to be extremely mentally ill to be bipolar. I then alternated between thinking I had bipolar and thinking I had BPD until my diagnosis of bp II last April. I still question the dx sometimes (though it has been confirmed-twice!-by other pdocs). My hypomanic periods are really mild compared to most, which often leads me to wonder if I'm actually unipolar. Truth is that I also have a ton of "non-manic" markers-atypical depression, short depressions (3 months or less), numerous depressive episodes, anxiety...so I really should stop questioning it. It's definitely something that is hard to accept.
