Emancipation: Is There Anyway

ok so im 16 and live with my grandparents in sc. i dont want to live here anymore and my mom in az said if your grandparents said its ok then you can live with me go to school get a job ect. i really think that if i moved that i would do better in school and get away from the people that i dont need to be around so life would get better. so i ask and they said NO! is there any way that i can get emancipated? or just leave?
