Mania is not always up. I have what is called "dysphoric mania" which means I am agitated, irritable, sometimes angry, sometimes rageful. I almost never feel remotely good when manic and have a hard time understanding why anyone would WANT to be manic although I do know that it is because mania feels entirely different to them. I've had the other kind of hypomania a few times but never for more than a few days.

I think for my dysphoric mania is part of mixed episodes but I think it can exist without being mixed as well.
