I find this very confusing. I think I experienced it once, but I'm not sure.

I've seen descriptions of it that to me sound like ultra rapid cycling (up/down/up/down many times in a given day) and other times it sounds kind of like an agitated depression (or depressive mania, if that exists?).

So what is it, how have you experienced it, and how do you distinguish it from other states?

Thanks!
