What are some symptoms of bipolar disorder?

Being really happy one minute, then really angry/emotional the next. It can last days, or weeks. It is just a rollercoaster of emotional highs and lows

One guy robbed a grocery store with a B.B.gun.One guy ran around naked.Many different ways,most cases becoming obvious without meds.
when your mood changes all of a sudden out of the blue. Like one minute your happy and laughing, then the next minute the slitest thing tics you off and your ready to kill somebody.
During a manic episode, you may be abnormally happy, energetic, or irritable for a week or more. You may spend a lot of money, get involved in dangerous activities, and sleep very little. After a manic episode, you may return to normal, but your mood may swing in the opposite direction to feelings of sadness, depression, and hopelessness. When you are depressed, you may have trouble concentrating, remembering, and making decisions; have changes in your eating and sleeping habits; and lose interest in things you once enjoyed.

The mood changes of bipolar disorder can be mild or extreme. They may develop gradually over several days or weeks, or come on suddenly within minutes or hours. The manic or depressive episodes may only last a few hours or for several months.

And thats BEFORE treatment. Then you get the wondeful experience of figuring out what meds and in what MIX will work for ya. 4 years and STILL getting that right. GOOD LUCK!!!!!!
