One day, my heart goes out to you. I agree you should leave the organisation immediately for your own sanity. I can't give you much advice, but don't rush into anything you may regret later, like moving too far away from your family and friends. Can you stay within a couple hrs drive? This way you can still see them on occasion but it will be hard for them to keep tabs on you.
Best of luck to you and we are here to listen and support you.
