Welp, it's fixed. I have to reinstall all my apps and games, but it's fixed. HOPEFULLY my saved games are on a Steam cloud or something. I didn't back them up though (didn't realize that was a feature on Steam until I just reinstalled it).
Sucks to have to reinstall them, but those are easy compared to handling the rest of my documents.
