To the people with anger issues: how do you cope with it?

So, I have anxiety and anger issues. i was able to control my anger while i was in anger management. whenever someone or something would upset me, i would simply ignore it and forget about it. but now i have gotten violent again. i throw and slam things, break doors, scream at people, and get physically violent. when someone gets me angry and i react in one of those violent ways, i just feel realllyyyyy weak and exhausted afterwards. i am out of breath, and i breath as if i finished a 2 mile jog. i practically collapse to the ground, and i can barely even move. my mind just feels like it shut off, and my heart hurts...sometimes i thought i had a heart attack! this weakness takes me a long time to get over- maybe a couple days to a week. and then while i am still recovering, i just dont even have the strength to get angry, because it takes up so much energy and makes me completely weak. yeah...idk what to say, i got issues, and im not good at coping with them. have any of you felt like this? and how did it make you feel better? please dont just say go to a psychiatrist...
