WOW, I almost just started crying.
I downloaded the update, restarted, went to use the bathroom, and when I came back, os x was up, and it had the original factory settings. I almost cried. Nothing I had downloaded was still there. I just sat there for a minute thinking "what the hell happened?" when I realized that I just made a new account so my family can use my macbook to surf the web if someone's on the main computer, and that I set it up so os x automatically opens their account. So problem solved, but that was a severe moment of panic.
