Bipolar Disorder is a mental condition that makes you go from extremely down to extremely high without any reason. It is caused by a chemical imbalance in the brain. The only thing to do for it is medications called mood stabilizers. They will lower the highs and raise the lows. Sort of leveling you out to even. There is no cure. If you have it, you will have it forever. With medication you will have a pretty normal life. I would recommend you go see your family doctor and discuss your symptoms with him, if he thinks you may have Bipolar Disorder he will refer you in the right direction.
Example:Bipolar means one moment your happy or sad or angry, and the next moment your the complete opposite. but it's like all of a sudden you change. and ask people around you if they noticed and you can find out if your bipolar.
