I would try to talk to your doctor more about it. I am diagnosed as bipolar, but my psychiatrist doesn't want to specify a certain kind. He says that my mood cycling is the most important element and that most people don't fit neatly into type I, II, etc. I also have other diagnoses that complicate the bipolar diagnosis, like you (PTSD, anxiety, OCD, Body Dysmorphic Disorder, and recovering from anorexia nervosa). I also don't get full-blown mania, but I get hypomania and severe mixed episodes.
