I agree that you should leave now. It sounds as if you are in physical danger.
BUT you don't have to leave this BB. We're not cutting you off from the opportunity to vent here and feel you have some contact with people who support... but the people here aren't in physically dangerous situations. You need to find someone in your area that you can get help from. Ask yourself: if you had a daughter in this situation, would you tell her to stay or go immediately?
