Someone get me a gun!!!!

SHOOT ME NOW PLEASE!!!!

For the PAST WEEK I have been working on a master to do list that my boss's boss wants us to do. Its a huge excel spreadsheet which lists all open files, their status, etc. One workbook. One sheet with my files listed and one with my boss's. We each update our own but keep it in one book. SHE SAVED OVER IT WITH A DIFFERENT SPREADSHEET SHE HAS BEEN WORKING ON BY MISTAKE. I am gonna have to start all over. I cannot even fricking believe it. Shoot me now, please!!!!!!

I hate doing things over. Its SUCH a pet peeve of mine!!!!!
