I live with my mom and younger brother and my younger brother is a huge jerk who only cares about himself and says nasty insults to me all the time and is annoying and bullies my mom and is just a horrid person to live with, but unfortunately I don't know any way to keep my cool while i'm around him anymore and at times hate him. I don't want to hate him but I don't know how to think in order to not let him bother me. I have told him multiple times how he comes off to me but he just insults me then, saying things like "you deserve it" or "you will never have friends if you can't take a joke" (his "jokes" are insults btw, like when he walks into my room when me and my mom are talking and interrupts our conversation and then calls us losers). He has no respect for me or my mom and if I could move out I would. I have never been bitter towards him or tried to hurt him, but in the moment when he makes me snap I do hate him and have to leave or risk hurting him. Please help, I can't be alone in having to deal with someone like this. And what's worse is I have to live with him, and he brings over friends who are just as bad as him and I seriously can't take this bs anymore.
