I am SO screwed.......................…

Check if your computer does automatic backups. If it does, you can go back in time a week or two before the master pword and you should not have a problem. But that's a big "if" and you may want to ask some friends to help you if you're not sure how to do what I just described. If that works, then it would be useful to tell you to not repeat that mistake again. Maybe use pencil and write the master pword underneath a desk, bed, or something like that. Good luck!
