What should I do about this situation?

I'm a 13 year old girl that had lived in Indiana for my whole life. Now, I've moved to New Jersey a loooong ways away from Indiana. I've lived in Indiana since I was born with my mother but because of her alcohol and drug problems, I moved with my aunt for a year and a half. My aunt started to hate my guts when her and my mother became friends again and she threatened to have me put in foster care many times. I'm a good kid I swear. I get straight A's and I have plenty of friends and everything. About a year ago, I lived with my father in New Jersey for about 3 months and it did not work at all so I came back to Indiana with my aunt for about a year. As I said before, she hates me and mocks me and all that. Her and my mother turned everyone in my Indiana family against me including my Grandfather, him and I were very close and he was the only one I could trust. I recently said I wanted to move back with my dad and I moved back to New Jersey about two and a half weeks ago and we are already having problems. I remember why i couldn't deal with him last year. Obviously, I can't move back to Indiana to my family and I'd have to go into foster care. My dad was my last option... I just don't know what to do anymore. Now, I'm just really stressed out and depressed. I don't know what to do. Every time my dad gets mad at me he screams and says "YOU ARE FORGETTING I AM YOUR LAST OPTION. FOSTER CARE IS NEXT." Now, once someone says something to you so many times, it's not as scary. I'm considering foster care.
