Hang in there. You did the right thing. If that is how your family reacted then forget them, move on. You most certainly did not deserve to be beaten; beating someone is against the law, no matter what the circumstances are.
You will find people you belong with. Stay strong and it will be okay. If you are in a big city, there are places you can go for help, called "battered women's shelters" (sometimes called safe havens). They will provide support and guidance for you, and keep you safe. If you don't know where else to look, just find a police station and they'll help you (you don't have to tell them your name or where you're from or anything).
Just keep looking forward; one day you might look back on this as the best day of your life. <3 -Jenny
