This is a tutorial on how to find and un-delete Writer temporary files; it also works for Calc files
If that doesn't work, as soon as possible do the following:
Download Recuva or PhotoRec (only one needed) and let it do an indepth recovery of deleted files on your computer. Examine files with approximately the correct timestamp. You may have to rename such files to .odt or .ods (depending on your original file type)
You may get a file containing some or all of your data (or not). Do this as a first priority; other use of the computer may overwrite any existing but deleted files and prevent their recovery. There is no guarantee that you will recover anything useful.

Not everything, unless you forgot to do your daily backup, of course. But
who forgets that? Nobody, I hope. Those who easily forget things probably
set up a schedule for backup anyway, like a Cron job or something similar.
So just recover your important document from your latest backup. If you
don't have one, maybe your document wasn't that important after all?
Anyway, did you have a question of some kind? I can't see it.
