It is called
bipolar illness and the bipolar means up and down. That's clearly what
happens. When people are bipolar, they can go from severe depression to
incredible exuberance and exhilaration. It is the movement back and forth
that can cause problems and perhaps be extremely dangerous. When people
are really up, they feel like they're all powerful, but when they go down, they
can be totally depressed. One of the problems is if you have someone who
is depressed and they rapidly gain energy, sometimes they act on it and they
can cause harm to themselves.
