Hello. Well I have an older brother which I suspect has antisocial personality disorder. At first my older brother would only not talk to my parents and my eldest brother because they usually came down hard on him for skipping school and other bad stuff he did, often resulted in shouting. He tried his best to avoid relatives also. As soon as my parents or eldest brother enter a room, he immediately leaves, stop talking, and changes to a more angry face. My older brother is someone that will take advantage of someone when given the opportunity and shows no signs of remorse. For Example, when I was on speaking terms with him I allowed him to play on the PS3 console I bought. Now at the time it was just money I saved up. I went on vacation and when I came back it was broken, and only two of my brothers where home, and he did not care that I paid over 600 dollars for it out of my savings. Both my older and eldest played on it, but it was my older brother that used it far more than he should. He also gets angry and irritated at which time he usually breaks things from in the confines of his room. One of which was my 60 dollar game CD. Among many other incidents I was treated like second class, and was often doing many things for him without anything in return. He almost every day skipped school and has not completed high school or intends to find a job or career. I was always taken advantage over, and for the longest time I took it all, until one day I just snapped and we got into a fight. I was often ridiculed by him for going to school and was told that I will not succeed, and that I?m stupid and such. The fight I admit was my fault. I was just building up anger until I exploded. I went looking to have a conflict with him. We haven't spoken to each other ever since, and that was just over 2 years ago. At first I was still rather angry at him, and was glad that I wasn't speaking to him. But he is stressing my family, and causing a divide in the family. One parent blames the other and other such infighting. I can still admit that a part of my hates him, and another loves him. He still only speaks to my youngest brother and sister. And those are the only two people in the world he speaks to. If we ever have to take him anywhere we practically have to drag him every time, and have to constantly work at him for hours until he leaves. Even for a simple haircut. If he is standing with eyesight of me and he knows it, he tries to cover his face with one hand just over his eyebrow and faces a little down so that his hand acts like an umbrella over his face. I have no idea what to do, and does this sound like the condition I suspect? Is there anything that I can do in this house that can help propel his mind toward his family and relatives? I am bigger and stronger than him so I am not particularly worried about him harming me. He often hides in his bedroom and I?ve been thinking about locking the door if he ever leaves. It is like a safe sanctuary to him and I think it may force him to interact with the family because the key is lost to his room. I am not a psychologist so I need help!!!!".
