Oh no! That's really unfortunate. I hope you're able to reconstruct your article.
I have some suggestions that might help to stop this from happening in the future. First, check out this website. It's a markdown editor with side-by-side interface that saves automatically like Google Docs. No anxiety necessary. Next, I would install a clipboard manager if you don't already have one. They're very helpful when composing an article since you copy and paste so many things.
I hope this helps prevent this tragedy from happening again any time soon. Good luck!
Thanks so much for the advice! I'm definitely utilizing it!
