Severe form of mental illness. To call it a mood swing is a understatement. It more like PMS on crack. Bipolar highs are characterized by delusions of grandure(thinking you can do more than you are capbable of). Lows are extreme anger or sadness.

Believe me. I live with some with the illness.

when you have no control over your feelings. you could be the happiest kid in the world one minute, and suicidal the next. you feel like no one understands you and no one can help you.
bipolar kid:

(mom comes in to check on you when you're in your bed reading)
mom: "hi honey, just wanted to check on you!"
kid: "ok. close the door all the way when you go."
mom: (walks out and the door is still open a crack) "goodnight!"
kid: (has a screaming outburst and sobs for the next 10 minutes and cuts his or herself. then goes back to reading as if it never happened)

seriously. this happened to me last night.
