My pro fell onto the floor and had a small crack from the inside creating glitched lines up the screen. That happened on 1/31

It’s now 2/8 and it’s gotten much worse

I have no clue about computers and don’t know what is wrong or what to do

Hate to say it, but you’re most likely going to have to replace the screen; if you arnt’t up for a challenge, you could take it to a tech repair shop, or you could follow the instructions found here. Heads up, this repair is pretty difficult, and might be out of your reach.
