I don't agree that you're bipolar. You're nowhere close to being out of control. I've known some people with bipolar disorder. When they're in a manic phase, they're loads of fun to be around. But then then manic phase ends and they're physically incapable of getting out of bed. It sounds like you've lived sort of a buttoned-down life and you're experimenting.
You're doing exactly what you say your doing: wildly flail[ing] about looking for anything that will make me [you] feel better.
I don't have an answer for you. I'm a hog for self-help books. Even if I don't implement a single word of what I read in any particular book, when things aren't going well, they improve my mood, increase my sense of being in control, tell me something about myself that I didn't know before, etc., etc.
