Angel, there are a TON of things we can say ... you're probably freaking out and need to take a deep breath and maybe google Bipolar Disorder and just get an idea of it before we answer questions. It might be a lot to take in at once ...
Wikipedia has pretty accurate information and broken down for easy reading.

If after you've read a little bit so what we say makes more sense you have additional questions, feel free to ask and we can answer as best as we can. *hugs*
