Draft disappeared when publishing

Hey there,

I had spent two or so hours working on a post draft, and soon as I clicked publish, and got “WordPress Failure Notice: Would you like to try again?” and when I clicked retry, it brought me back to my post, but all my content had disappeared, is there anyway to retrieve this?
