I know that feeling. Did something similar myself many years back. I forget the exact details (dissociative amnesia?), but I wiped nearly 4TB of data with an errant command, and spent days trying to recover it from the drives to no avail. Don't beat yourself up, it happens to the best of us, even to someone like me who shouts from his soapbox about the virtues of multiple backups.
So what about those multiple backups ...
When I went to recover my deleted data from a redundant backup on an external HDD, the drive decided to crap out.
So the combination of an ID-10-T error and Murphy's law did me in. Fortunately I had some of it archived on many smaller drives, some on cloud services, and some shared with friends. After a lot of work collecting and comparing versions I was able to recover a good percentage of it. So hopefully you will be able to do the same.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
