Hi,
In order of a likely sucessful result
1. Use your backup.
2. Use your IT departments backup
3. Did you mail it to someone, check your sent items.
You are going to have a very bad day indeed and It will probably not make
you feel much better at the moment but in future remember to always back up
your work.

When competing hypotheses are otherwise equal, adopt the hypothesis that
introduces the fewest assumptions while still sufficiently answering the
question.
