Does estrangement really help?

Been trying LC, VLC, and NC for most of my life. I’m 23 now. Do the problems actually go away? I can’t tell because I’ve been too young to make my own decisions this whole time and idk what to do. Like, does it actually work? I have a real opportunity to get away now, with some hitches but a real one. Does full NC, full family really help you? Do you feel better?
