Im 14 years old, im convinced my brother has anger issues. He would always annoy me and wouldn't stop. Like bullying. He used to punch me in the head several times when he got angry over me simply pushing him(lightly). I would tel him to calm down and try to leave the room, but he would persue me till someone broke it up. Sometimes ive been locked up in fear in my bathroom when no one else is home after he tried to kill me. Im convinced he will try to kill me. Today, i told him to get out of my room because he was very annoying, he would keep on picking on me. So i pushed him and told him to get out! He then got into his mental/ anger state. He had his fighting face, he tried to punch me so to defend myself i had to try to avoid being killed and feared for my life so i tried to hold him down till my mom came. He ended up breaking loose and punched me 3 times. I am much smaller than him. We are both 14 he is bigger weighing 150 and i weigh 130. He gets angry very easily and i dont know what to do. These scenarios happen daily. My parents even get him in trouble but nothing works. I NEED HELP, once he jumped on me and delivered 10 hard punches to the head i fainted by the time my parents came to break it up. PLEASE TELL ME HOW TO DEFEND OR SAVE MYSELF PLEASE!! I fear for my life. I was thinking of buying a security camera in my room.
