Should I return to my Mum or stay with my Dad....?

I was born in Yuma and lived here til i was... 4.? 5.? My Mum left my dad, taking me and my lil brother JJ to Mesa. I lived there most of my life. I have everything there, my brothers and sister, Mum, stepdad, Gammy and Pappy, Uncle, Aunts, Cousins Friends, Pets, my 2 besties Johnathan and Daniel, and they guy i like... I had a bullying problem and moved here for the last 2 months of school, by here I mean Yuma with my dad. I have family here, but not many of them like me. I have friends, alot of them, but I can stay in contact through fone and Facebook. I thought about moving back to Mesa, but thought about how much I'd miss all my friends. I thought about staying here, but i miss everyone in Mesa. Every night i cry because Im homesick. I cant stand being away from my home. But i wont be able to stand being away from my friends... :/ i dunt know what to do.!
