I feel so badly for you right now. I really want you to talk to somebody. There are crisis lines that you can call for mental health. Or call your local mental health center. Let them know that you are 13 and that you are having anger problems and you are afraid for your own safety. I bet that they would help you for free. You don't need to suffer alone. Get some support from somebody. Being you are from another country, I don't know how things go there. I just know that you are in a tough spot and need help. I will do what I can, but I can't replace professional help.
Hugs to you and best wishes to feeling better. Keep posting. Maybe somebody here can help you some.
