Ugh. I do. And my mood often changes on a daily basis. (Though every so often I HAVE hit a long depressive phase, but it's only happened twice in the past five years.) I literally get NOTHING done unless I become manic and I feel angry. Then I clean, because I've become so messy that it's getting impossible to walk in my room. But yeah, I actually went down full grade levels in several classes in my last quarter of high school since I was just so out of it with my moods & such (a 92 to a 75 in AP Lit). I don't know how I passed all of my AP tests when I couldn't focus enough to study.
