I guess so. Don't live there, don't talk with them. Hopefully, you aren't needy because that would be the last thing I wanna hear. At least have a source of $, that's my point. Don't blame them, we all come from fucked up families, my mom tortured me when I was little but I don't wanna go on about me, just saying that I know how a toxic environment feels/looks like. ''My family doesn't want me to move out''... they don't wanna see you further, they wanna see you stuck there. Try and have one last conversation with your sister, see if you can make a sane train of thoughts out of her, if she has the same mentality, then run. You can't live like this, it's suffocating. Are you and the kid's father still in good terms? It doesn't matter if he's the biological or the step-father, a father it's father, you either have it in your blood or you don't. If you are in good terms with him, see if he can help you for a little while, like you know, leaving your kid off to him and then fix the situation.
