My project has 'disappeared' meaning it changed into a black background.

My question concerns the application Photoshop. I had a graphic project that I had been working on for a long time. Today I opened it and the entire project has "disappeared" in the sense that all that is in the file is a black background. Can someone tell me if it can be restored or something?

Did you store the file locally? 

What are the image’s pixel dimensions, Color Mode, bit depth and its current size on disk? 

If the size is laughably small compared to what it could reasonably be expected to be then I am afraid the file may have been damaged (on the hardware-side) and your only hope might be a back-up (if you employ any back-up system).
