Hi I am guilty ,I bullied my brother very badly for years ,I am 7 years older than him ,when he was 4 years old I locked him in a dark room for no reason ,I bullied and used to him and slap him for no reason and and when he used to get scolded from my parents I used to laugh at him ,when he was bullied by some students 10 year older than him ,I blamed and shouted at him when he came home, he used to ask for help when he was getting his arm twisted but I used to ignore him ,he once said that he wanted to commit suicide ,I treat him right now and have promised my self to not do it ever again ,but I am so guilty
