People try to wind me up?

[Bob Ganja]

People Know what im like and they know i switch easily, Like certain things they can say make me go mad. They know im a big man when i fight they know i break bones when i go for it. Ive put people in hospital when i fight aswell. When i try and keep myself from going mad and walking away they say im a pussy for walking away. I know im not and i know they know im not but it still switches something in my head and makes me go mad, How can i stop this from happening, I like the feeling of hitting the person that made me switch. But the problem is i cant stop when i start, untill their lying there shook, crying and begging me to stop. The other day a big man i know whos older than me tried to start with me and i managed to walk away but it was at my mates house so i went into the other room but trying to clan myself down mentally it just syks me up and makes me get madder and i ended up going at him and kicking the shit out of him, I didn't want to and soon as i stopped i almost broke down seeing the black eye(which had already come out) the snapped nose and the loads of broken teeth that were falling out of his mouth. I said i was sorry the next day and he was cool with it and said he shouldnt of pushed me. But how can i stop from getting like this. I really dont like it and will cause alot of problems for me.
