Alright ladies so lemme tell you a story. I am 20 years old, my younger brother (the problem) is now 18. He has no liscence, and works three hours one day a week. He cusses at our mom, punches holes in walls when he doesn't get his way, gets up in our faces and screams and yells when he doesn't get his way, talks in circles, and says generally stupid things when in arguments that don't make sense of add up based on what happened. He is at my mom's house all day every day of the week (except one for three hours). My mother asks him to do things around the house constantly (ie cut grass, dishes, take trash out). The things he is asked to do are painfully simple. He failed out of highschool and seems to think somehow he is going to buy his way into a college (even though he barely has a job). We'll this tonight I was pushed over the edge. I was driving him home from work when he decided to begin to tell me how stupid I was for taking a 10 hour shift to pay for college telling me to "shut up" loudly and defensively when I tried to talk. So I told him to get out and walk home. So when he gets home my mother tells him he can stay outside until he's ready to act normally, to which he begins all manner of absolutely TERRIBLE name calling and banter... TO OUR MOTHER. No one knows why he acts this way but he's been doing it since he was old enough to think he could scare us into doing what he wants because he's a big guy now. Well ladies, I am officially sick of this shit. It's time for me to stand up for myself. I'm looking for advice. Maybe even things to do to passive aggressively make his life as misserable as he has made ours (me, my mom, and my two sisters) for nine years. Please help me. I moved out when I was 18 because this asshole was destroying my mental health and now my family's too.
