Ouch! That DOES stink! But you DO have your story saved on your computer, right? That way, you can still re-post it, can't you?
I think, the worst thing for me would be if I completely lost one of my stories. Even if I didn't like it, I'd still be horribly upset by that.
Hopefully, you still have the story saved and, though it stinks that all your reviews and everything are gone, you can still re-post and maybe even get new fans out of it.
