I also had uncontrollable rages prior to my diagnosis. I would snap and the me would dissapear. Often times, I did not even recall my actions. I have broken countless cell phones and what not.

Definatly talk to your doctors, let them know what is happening. Once I began treatment for bipolar I have only had a couple of instences of the scarry me comming out to play. I do not make excuses for what I have done, but I can honestly say that I was not in control at the time.

I am not sure if this is exactly bipolar or something comorbid, but with treatment I am the real me most of the time.
