I would say he is narcissistic. It doesnzt matter what you do or say, he will be right. He claims you are either lying, you have a mental problem or are just plain stupid and deserve it all. The sad thing for him is, it`s not true and those who believe him are scared of him also. He has them under control. I would suggest getting a teacher, friend`s parent, neighbor or someone to go with you to the Dept of Human Health and talk to someone there. I know how you feel, my brother and sister both had been taught how to manipulate, humiliate, threaten and destroy people they saw were above them. You are above your brother and all the people who sit back and allow it. He is wanting to see your anger. Until you get help, don`t let him see it. Cat`s don`t play with the mouse after they`ve killed it. Play dead, so too speak. Don`t talk, don`t fight back and stay to youurself as nuch as you can.
