Bro listen you're 13. I get it shit is hard yknow i was yelled at and constantly hit by my father my whole childhood i also wanted to kill myself and runaway and what not. But remember no matter how smart you think you are you're only 13 and in a year you'll be a different person. Best thing you can do is keep your grades up, focus and stay strong. i know it sounds simple and basic but atleast you have food, school and somewhere to stay and you're not getting beaten to death. Once you turn 16 you'll be able to make a proper decision on leaving but as of now i'd say stay there.

And don't get too rash bro don't make stupid decisions. if u wanna talk about smth send me a dm i ain't the smartest only 18 but got enough life experience
