I hate it when stuff like that happens, Marie. It's so frustrating to put effort into something, just to see it perhaps vanish into the vast online ether--and this can happen with a mere inopportune click of the wrong button.
I can't advise on any kind of 'work in progress' folder on the site, but I would encourage you to reconstruct your story as best you can. It is meant to be, friend...and remember, nothing is ever truly lost anyway.
