Please help me: What should I do when I want to leave and not burden anyone anymore? Where should I go?

I feel very sorry about your family problems and i understand your anger management but if you really love them and if i were in your shoes just try your ABSOLUTE BEST to never say anything mean or hurtful or rude or back-talky and always tell them that you love them and that your sorry for being hurtful, and just try to be the peacemaker. Because every family needs one of them. I hope i helped out in any way. Stay strong <3
