COMPUTER HELP, URGENT (Please see details)

Okay so I had my coffee behind my computer, and I was trying to kill these fruit flies that have been annoying me all day. One landed on my computer screen, so I hit it. Needless to say, I killed the damn bug. But now my computer is all screwed up because coffee splashed everywhere. I dried it as much as I could, but now there’s a “bubble” forming at the bottom of the screen that is brighter than the rest of the screen. (and it is slowly getting bigger.) There is also a line that is slowly increasing in size. WHAT CAN I DO ABOUT THIS?
