>>19774dude, this is gonna be hard to hear, but they already hate you; that's why they're abusing you. This isn't love, it's hate. Being homeless will be a better option than being under that roof. There are options, there are centers which take people in, there are even mental hospitals which would definitely take someone like you right now - and that doesn't make you insane either.
Just because people have it worse doesn't mean you don't deserve better. Please take the reigns in your own life and seek the freedom you deserve. You can get out of this, it just will take effort. I know you've been worn down and you're tired now, but that's what they're counting on.
They are using you for your money to live a life off of you. You are their slave, not their child. That is all they see you as and that is all they will ever see you as and you do not deserve that on the pure fact that you are a human being. No human being deserves that. None. You deserve better, and you can have better. You just need to take it with everything you've got.
Pester the bank, pester the police, pester the church, pester your neighbors, pester whoever the fuck you need to to get out of the situation. It doesn't matter if it mildly inconveniences them, and if they care even a little modicum about the situation, it won't be an inconvenience I sincerely promise that.
