I dropped my iPhone 4S and the screen won't work., Please

I have a withe iPhone 4S from AT&T. I recently dropped it (this morning).It was a pretty hard fall, yet it didn't crack. The screen stopped working, though. I tried restarting it, turning it off, charging it, etc., it just WOULD NOT WORK! However, when I plugged my phone in to charge it, it vibrated. I think the screen isn't working, but the phone itself isn't. Also, I've had this phone since December 2012, if you need to know.
