I really don't think you understand the relationship between bipolar and anger. Medication presently used does not work in my family, who all have some form of mental illness, from bipolar to social anxiety to schizophrenia. These were inherited. These illnesses do not mean we were stupid. They mean probably that something is wrong because of a chemical imbalance, caused by our genetic makeup. Lithium does not work for us. With other medications, the cure is worse than the ailment, and they only bring on other illnesses, like obesity, dullness, etc. Anger is a tool used to stimulate someone to bring them out of a mood of helplessness or dullness.
I think people should learn a great deal more before they begin to teach. Some therapy is not only useless, but it depletes people of what little money they have, and sets them off on the wrong track for a cure.
