Anger is a force to be reckoned with for me too. Before i was diagnosed I used to punch/break everything. All the doors in my house have holes or cracks in them. I have broken about 5 windshields over the years- all for reasons I dont even remember. I have yelled at people I love, people I hate, and people I dont even know. I assaulted a teacher and a security guard while I was in High School and was kicked out for a while.

Get some help because it doesnt get easier without it.

Exercise helps. Punching bags are great. It helps to set aside time to CONCENTRATE on relaxing yourself-deep breathing/meditation or simply (slowly) drinking a cup of tea over a ten minute period.

Be proactive and help yourself. Good luck.
