I do not feel safe in the house with my mom ( 17 yrs old), can I be escorted to my dad's or grandparents house?

My mom received a custody change that my sister ( 15) and I (17) want to live with our father. He has a temporary protective order from my mom that she placed because my mom has faked and lied in court about our dad trying to stalk her. My mom is very vendictive, and we are both scared to stay her especially since she just got the custody papers. Her, my sister, and I got into a VERY heated arguement where she was calling my father a physcotic idiot and told us she is trying to get out of this house as soon as possible because she never wants a thing to do with us again. She was up in my sisters face yelling at her because she was upset and calling us maggots, physco, & stupid. In the past she has told me to throw up my guts ( suffered with extreme bulimia), go kill myself, ****** lover ( have dated a black guy), etc etc. I feel threatened here, and she keeps yelling even with my special needs brother in the room. We both feel threatened and not safe. Do you think that the police could escort us to our granparents house ( dads parents) because my dad is 300 miles away right now in florida on vacation ( we live in georgia). Please please please help us!
