Why won't my touchscreen work with my fingers but the stylist?

Today during class I accidentally dropped my Chromebook flat on its screen while trying to show one of my peers our project. I picked it up instantly and examined it. I think it looked perfectly good until when I tried touching the screen, I noticed it would not respond to my touch. I took out the stylist and it worked perfectly fine. Further more, I somehow accidentally disabled the touch pad. So now I am stuck with using it like a tablet with only the stylist. I cannot even use Autodesk Sketchbook; please help.
