Cracked iphone 5c on the inside?

Well, I just got an iphone 5c for Christmas. It was 500 bucks! We aren't event done paying for it yet! Well anyways this boy had bumped into me at school in the hallway and I lost my grip and dropped the phone for the first time. It was in a case. And now my phone won't turn on. It's not because of the charger, I've turned it on and off, I've called the phone on FaceTime, the LED light flashes but the screen is black. I have no money to fix it. None. What can I do?

First off, have it in your pocket when walking. Paying a bill to fix it will be a good reminder how to take better care of it.
