Any USBs it could be on? Or did you email it at any point? Is it possible that there's a back up computer version saved under the first line of each chapter rather than the title you gave it?
Even if it's not there at all, you've written it before. Sure, it'll be incredibly annoying to have to type it again, but not nearly as hard as it was the first time.
I only ever emailed the prolouge, which is why I have that.

Yeah. . . . but, it was better the first time, much better, now it's getting kind of dull. I found a hard copy of the rest, either in a previously printed version, or a very rough outline of the chapter. >.<'
