My advice: see a psych doctor, get medicated. Also, keep a mood journal (I did the whole time I was hypo, but at least I didn't totally crazy manic since I am type1), exercise regularly, get up the same time every day, and try to go to bed the same time. (I know, basically impossible in an episode) Avoid drugs and alcohol, risky situations, etc. Watch your money, cut up your credit cards, etc.

Good luck.
