Please kill me

my family fights a lot with my brother, it’s been going on for years...nothing stops. He’s verbally and physically abusive on me and verbally abusive to my mom and dad. Today he punched my door and broke it. I’m so fucking done..you may say..”why not hang out with friends or school stuff:)” well when you’re put down and criticized for 15 years..I developed anxiety...my parents never encouraged me to do stuff and never really compliment me. I don’t have anywhere to go..I moved to South Carolina and it feels like a trap because I’m trapped at home. School feels like a prison where people are always watching, at home I feel like I’m going to die. Fuck this state. I’ve tried so hard to know people and they all treat me like shit. I feel really mad at myself. I can’t end myself because of my boyfriend, who’s “depressed” .. I don’t see myself without him..I know you may say “aww it’ll get better” no it’s not. I will not be messaging anybody. If I had to say one last thing to everybody on earth, it would be: watch others before you watch yourself, and take care of others...even if you don’t know then, you can still watch out for them, talking to them too. I’m really alone...
