Screen displays static and wont open properly. How can I fix this?

Accidentally dropped my phone from my sink onto the bathroom floor. When I picked it up, the whole screen displays static with different colors. Though I'm pretty sure it's still working since messanger notifications are still going off, I haven't tried anything yet since I'm scared I might do something to make the situation even worse. Is there any way to fix this or will I have to say goodbye to my phone?
