Jayy - brave step you took. i think you did the right thing. i wanted to suggest it but was afraid you were so dependent upon the living situation that it would either be impossible for you to do - or that you would find it too traumatic to leave one of the few sources of (admittedly mixed!) emotional support.
you are taking control of your life. that is such a good thing.
