I don't know what to do.

Okay. This ISNT about my S/O. But my older brother. Keep in mind I am 19. 
He's 21 and constantly being kicked out for crap he does to my mom. But lately he's gotten a lot more violent NOT towards my mom or my little (16) year old brother but me. He has hit, kicked, punched me and slammed me against our fridge he has told me to kill myself (he knows I've tried before) he has told me that I deserved to be raped again. And tonight. Not even five minutes ago. Fractured my hand because I went to grab my food. And I've told my mother and she has tried to do everything she can but he guilt trips her, mentally abuses everyone in the house, steals money from everyone including my aunt who is visiting with my mom for 10 days for the first time in 25 years. And this has been going on for a little over a year now. Just after he was arrested for aggravated assault with a dangerous weapon. I have tried to talk to other people about this but I have gotten no help. It's gotten to the point where I'm scared to come home or even be around him. And ladies (and men) you're the only ones I have left. And I don't know what to do anymore.
