Mac splits screen horizontally and glitching out of nowhere

So I opened my laptop today and it was working perfectly fine, then all of a sudden the screen splits in half horizontally and now it’s glitching on the lower half. I did drop my laptop about two years ago, don’t know if I’m facing the repercussions now... but nothing I’m doing is working. I tried resetting the NVRAM and the SMC or whatever it’s called lol. I’ve tried doing safe boot, and holding down the edges of my screen to see if there’s a weak spot, which doesn’t seem to be working. I’m just not sure what to do. Doesn’t help that I’m a broke college student either. Does anyone know of any possible solutions?

MacBook Pro 15", macOS 10.15

To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.

Thanks, I tried safe boot and it didn’t work, then I also checked the other users and the issue seems to be universal.

From Recovery you can reinstall your macOS on top of your existing macOS as a refresh of the OS.
