I can't stand it!

I hate addressing selection criteria! I sat down just now to try to finish it off and it's not there. We spent a few hours on it last week and now it's not there! It's gone! Disappeared! Obviously I forgot to save it! I called John to break the news secretly hoping he'd say "forget about it. I've just been offered a better job and I'll be earning hundreds of thousands and won't have to do anything for it" (John's ideal job) but no. He says "Oh well, I guess we'll have to do it again" as cheery as can be. It's got to be sent by Wednesday to arrive in time but I've got nothing better to do. So I'll just spend the rest of the day crying and hope that tomorrow I'm sick or something so that I don't have to do it.
