Oh, I get like that. Don't worry about it being uncomfortable or bipolar, good things can come from restlessness. Try laughing in fun voices, let your thoughts race, follow an idea or twelve and call someone up, go out and be silly, get laid! Write a book, cut your hair, learn to play guitar, fine a new job and don't do anything excessively reckless, moderate recklessness leads to experiences you wouldn't otherwise have.

You don't have to worry about losing control, you're already holding yourself back with excessive worry, loosen that grip.

Or attempt to sit still, fight the energy and worry that you're losing it...see where that gets you.
