I may wind up homeless tonight, but you know what? Fuck all if I do. I'm tired of being invalidated by my own family. If they have a problem with it, they can get the fuck over it or cut me out of their lives. I don't care, I don't need any of them.
Good luck mate, sometimes old generations can understand these kind of things, but hey, you're family, sooner or later that'll be more important than anything.
