Arrgghh

I haven't posted for a week because of a major crisis. Last week, I was rewriting in No Need to Wait... When I change a chapter, I create a new document so that I can cut, paste, rewrite, amend, change, add, subtract, edit, fix, arrange, and revise to my heart's content. Once I settle on the new version of a chapter, I cut it and paste it into the original work. Feel the foreshadowing?
I selected "all" in the main document, added the new chapter and hit save. I had an inkling I had done something wrong when the process, which is usual instantaneous, took about 30 seconds. Indeed, I had mistakenly selected the whole book, not the chapter. I lost everything, including all the revisions I had done in the past two weeks, but the one revised chapter I had just completed. Did you hear the scream? If you'd been listening, you would have.
 I thought of Maxine Kingston. The story I heard was she  had finished a manuscript, printed it off, and readied it to mail to her publisher. She left the new born book on her desk, safely wrapped in a mailer and went out for a while. The Oakland fire broke out. I'm sure she tried to get back to her house, but the fire department wouldn't allow it. She wasn't able to return to rescue her book or the computer (these were not the days of the cloud). She lost everything. I can't imagine what she felt.  
Anyway, I know all you computer savvy people would have known how to recover. I didn't. Instead, I went back to the most recent copy I had and started a piecemeal revision. It's back together. but I am mentally exhausted. I've sent it off to Katie to do her magic.
