I didn't know all of these years why my mood changed so quickly and so drastically. I was misdiagnosed as a teenager and untreated for the past 7 years...I finally sought help and the Lithium they put me on made me gain 20 lbs in a month and did not work. I am highly upset about the medication and I am waiting on medical assistance until I can get to a psychiatrist! A crisis center put me on Lithium!! My current circumstances are making my rage horrible!!! I hate being Bipolar!!!!
