If one week I'm really happy, productive, and hyper then the next week, I won't get out of bed and I sleep a lot, and think of suicide. Does this mean I'm bipolar? Because I had vivid dreams recently that I or someone else tries to kill me and I would wake up crying and shaking looking around to see if the is anyone in my house. When I'm happy I don't go to sleep til around 2 or 3 in the morning but I get 8 hours of sleep but when I'm sad I sleep over 12 hours a day. If you think I am bipolar, please tell me.
