Hi Agony,
I don't know much about bi-polar, although my sister has been diagnosed with it but your RAGES title got my attention since I'm dealing with anger issues.
I can say when I was on meds for my anxiety my irritation level seemed to increase if I wouldn't take them consistently at the right times. Could that be it?
If not then, I don't know.
I'm sorry you're feeling soooo mad and angry. I understand. It makes you feel horrible about yourself in the aftermath. I'm exercising and hoping it'll help me with my anger. I'm not sure if exercising will help for you though.
I hope you find something that helps you through this.
