I know what you mean, when giving my psych history I usually say something like "after the terrible two's I never stopped having temper tantrums"

I was punished for being angry the majority of my life, not one disciplinary action worked against it. I was also punished for being depressed and not being able to enjoy much of my childhood. I think there is no medication to treat anger, don't feel bad I beat inanimate objects up to, it was the best coping mechanism I ever came up with. I used to hit walls and break stuff that I cared about in fits of rage. But since I injured myself really badly punching and breaking stuff a few times I learned my lesson and now I punch softer stuff. I also found exercising instead of punching stuff helpful if you can catch it before you get too angry.

What happens when you get this angry that you feel the need to hit, something triggers your primal fight or flight response and you get overtaken by a lot of adrenalin. By exercising you are using the "flight response" instead of the fight aspect and your adrenalin doesn't go to waste and lets you release some of that pent up energy in a positive way. Plus if you do something positive with that negative energy you feel good about yourself afterwards and do not feel the need to sulk and cry about it later. I noticed a reaction I have it goes in this cycle: first comes anger, next comes anxiety and finally remorseful sadness.
