Urgent! Lost one year worth of diary in draft folder

I'm desperate, for my almost one year worth of diary saved as draft mysteriously disappeared (as of about 1:30PM China time on August 15, after checking the history), I wasn't aware of it until after 22 hours later.

I've tried everything possible, all things I knew and learned from online, but nothing helped. I have no idea what happened, I am positive no hacking in the picture. That was the only file I was editing when this happened. I didn't manually do delete, I don't know what happened.

Please no need to list anything typical such as "deleted folder recovery", since it doesn't apply to my situation.

I'm writing just to see if it is ever possible that you could help me dig out the lost email on your server, anything that you might be able to do to help. This diary means so much to me, it just kills me inside knowing it is gone without a trace. Please help, if you can, to get it back!!!

Thanks a million in advance for your kindness. I wish I were a FBI staff now :(
