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.
"the scariest thing about abuse of any shape or form, is, in my opinion, not the abuse itself, but that if it continues it can begin to feel commonplace and eventually acceptable."
