You can breathe a sigh of relief... I've stepped down off the ledge.
After a day of
moping cleaning house... folding laundry is cathartic... a clean sink just makes me feel good... I finally gathered the courage to push the button on my antiquated laptop and it said....
"Windows is loading..."
I haven't reviewed the damage. but I've backed up the rescued copy of my novel, as well as the "pre-rescued" version. With luck, I've lost no more than the final 1/2 hour of so of yesterday's editing.
