I am severely irritable.I have boundless amounts of energy. I haven't slept in days.My speech is very fast and pressured. I have all these ideas flooding through my mind.

My family is starting to get worried about me. I see my psychiatrist tommorow and i am going to show her what i have wrote here. Is this mania?Do i have bipolar disorder?Thanks
