I actually feel the same as you. I feel myself feeling comfortable in both male and female roles, but I also deal with bipolar disorder. The transition between genders, or how masculine or feminine I feel, seems similar to that of the transition I feel when changing from Manic to depressive, or Hypomanic to dysthymic. I feel that I'd like to pass as both male and female but being born male and finding that out is a bit confusing, especially when dealing with a mental illness. Dysphoria sounds like a cure all when you look at it, especially to someone with a mental illness. I latched onto the idea that I was a girl pretty fast. But now...I don't know. I'm fine when people use masculine pronouns with me, and when the kids at work call me Ms. Ben. (Ben is my birthname, and they don't know any better than to call me that and I find it adorable) I want to wear dresses and flannel shirts and work boots in a matter of speaking. I just want it all it seems, haha. I'm glad I'm not alone here in feeling this way.
