Eventually in the fight I grabbed her hair and slammed her body into the tree.
Why would you go that far to harm her like that?
She has been such a pain in the ass to me and I hate her for any reason.
It's understandable one we're in a state of mind when were really upset we could do things to harm people. Physically assaulting someone and grabbing them by the hair is extremely wrong, if you're in a situation where you're upset with somebody you should try to work it out by talking with them. Continuing to try to resolve issues by assaulting people is going to result in you having issues with the law and having people upset with you.
I know, in that state of mind I wasn't thinking right.
I highly recommend you seek some professional help for your anger issues. Assaulting people like this is extremely dangerous to them and like I said potentially get you put in jail.
