Help me get to california!

Recently i moved from california to florida, im16 and in a really bad family situation w a not so great dad and i cant live my own life at all. hes been abusive for as long as i remember, and controls everything he possibly can, pulling me out of school, locking me in rooms, taking everything i own, destroying my belongings, verbal and physical abuse, etc. i want to come back to california where everything i know is and start moving forward in life, and not to mention get away from my  father. My grandparents on my dads side after seeing how he  treats me supports this and said i shoud leave, but they cant afford a ticker, neither can i.  Im hoping to get a plane ticket but i have no money, my dad takes everything i make. all the money here will go towards getting the plane ticket for me to go to california where i have a place to stay, can continue school, get a job, and start moving forward in ways my dad refused to let me with his controlling ways. im hoping to get out of here in the next 2 weeks... $300-$400 will go to the plane ticket and if theres any more, itll go to getting on my feet out there (clothing, food, backup money.). This is my last hope, my last shot at getting out of here and back to the place i love and thrive. Any help you guys can give, please do, and share. thank you so much.
