Besides being DXed with Bipolar-II(mild) I was also DXed with ADD at the same time, people can have more than one DX, but I find what the ADD does to my life is the depressor, rather than the opposite. They said they wanted to wait awhile to stabilize the bipolar side, then they would go to addressing the ADD.I have become so tired of docs saying it is the depression causing all this havoc, finally I said to my pdoc,"you have been treating me for bipolar for 5 yrs, I have not had any episodic behaviour, (I never did) I was told we would address the ADD after we saw how I did with the bipolar meds. now if you are not going to help me with the ADD part of my duo DX, then direct me to someone who will (there is a group of pdocs at this center)". I exclaimed, that I wasn't threatening him by saying that, but I had enough, this ADD is ruining my life, then he started me with Concerta, I'm still titrating but already see a subtle change, sort of like proving my personal theory.

I knew that has been my problem for years, my experiment was while I was on diet pills for weight (stimulant) I did great in college, honor roll twice in a row. When I was a kid right up to HS I was always failing and what not. Kind of tells you something, eh?
I had to stop the pills, doc felt it was leading me into bipolar or triggering it. I know it's the ADD that is most of my depression. It is possible that is your case too.
It is hard to tell, not knowing you, but I do believe the ADD leads to anger and depression, due to the frustration we suffer from this disorder.
Take care now,
