You must deep down enjoy being angry. Why else would you let all this stuff send you off the deep end? If you stick w/ AA for a while and start paying attention, you'll come to realize that there are no mistakes in God's world. Everything is exactly as it's supposed to be at that particular moment in time. If you begin to accept that, then you won't allow circumstances to anger you. You will be able to take total control over how you feel.
Like the Taz, I believe very strongly in the Serenity Prayer. If you say it often enough, and if you take back control of how you feel, then you're going to find serenity. And then you can serenely walk into the courtroom and sue their a***s off.
