The screen is black and unresponsive, but the phone still works.

Hey, so yesterday I dropped my Google Pixel 2, and since then the screen has been unresponsive. The phone itself is actually on, as I accidentally called someone, and my alarms have been ringing all day (I can't turn them off). Does anyone know what to do or what might be wrong? Any and all help would be appreciated, thanks~!
