Noooooooooo!

I'm working on a kids' novel called Black String. I've spent about three weeks doing major edits, based on the direction of my agent, the esteemed Abigail Samoun. Today when I opened the Word doc, the file was corrupted. I've been trying with no luck to restore it, rescue it, something. 

I am astonishingly frustrated. Is it time to abandon Word for Google Docs? 

Bleah. I feel pretty unmotivated right now.
