I'm so sorry shattered sanity about what your family is doing. I don't know laws where you are, but here you would be able to get a protective order that if they did come within a certain distance of you, they could be arrested on just being there. Some orders also include phone or text contact, but that's a little harder to get here. I totally understand the fear of the police as well tho, I just hope that you are able to feel safe from them...
