How about asking your regular doctor to refer you to someone else?
Once you get there, then you can tell them about this previous creep.
Who is she to decide whether you get more treatment or not? Not right. Maybe not legal. Don't give up. There has got to be a way. Call for an appointment and don't tell them you're changing over from her. Your medical past is YOUR business, if you don't want to share it, you don't have to. Patient privacy rights. Or just tell the new place, we didn't fit well, or I wasn't comfortable with my last doctor, and if they ask who, just say, I'd rather not say right now so as to get a fresh start.

gggrrrrrrrr! I hate doctors who confuse themselves with God.
