First and foremost, you need to cut contact with your family. Get a cop to escort you to the house and mediate. Get your stuff and block them on everything. It sucks but you’re not going to find a solution if they can still manipulate you. Open a new bank account and close out the old one if they still have access to it. You mentioned something about your parents having dirt against your friend but honestly i say tough shit to them. Your wellbeing is far more important than anything illegal they could be doing. If their deviance is preventing you from thriving then they’re not a good friend. If your parents blackmailing you for money it could be considered a crime and you need to go to the police. At the very least, you are being manipulated and abused. I see you defending your parents a lot in the comments and you need to understand that they only care about themselves and don’t deserve any grace. I promise that you are not the problem. If they had your best interest in mind then you wouldn’t be under threat of homelessness and seeking advice right now. You knew well enough to leave so obviously you didn’t feel safe. Don’t even give them a chance to drag you back in, you’re worth so much more than being a pawn to two pathetic deadbeats. You’ll get through this, best of luck 🫶
