This is true for me as well, to an extent. When hypomanic, I may be so self involved that there is nothing to get angry about, but when someone is persistently causing me problems i can go absolutely bonkers. And it's not my normal, anger then sit down and have a bowl of cereal, anger, it is more like something that just perpetuates my mood in general and makes me a bit more unstable.

When i'm depressed, I get mad when people tell me what to do i guess.

I think i get angry most often in between cycles
