Holy crap. I didn't recognize the new account name at first. My mush brain didn't allow it to sink in. So sorry to hear about losing all that data, especially your keys. Yep, sometimes lessons are learned hard, but that is okay. You will build your account back up rather quickly I am sure.
It was the most face palmy day of the last year I tell you, but no worries, it's now history and I'm moving forward. When I'm feeling really stupid, I go onto YouTube and watch gun safety fails and feel instantly not so annoyingly dumb afterwards 🤣
