Or known anyone that has? What happened?

I think someone is trying to "hack" my stuff, my ebay account randomly got permanently suspended for "suspicious activity" and more seriously, my Robinhood account just got froze for the same reason. I'm thinking I might need to change all my passwords and start adding authentications and sh cause I know this stuff can get pretty bad...

Yes and please check your credit reports.

feel like I lost my old identity after she left

Dang man what happened? Was it difficult to recover from, and did you ever make a full recovery?

My credit score was the only thing affected. It dropped 200 points, and I saw someone had opened so much s*** under my name and had collection notices.

Had to go through two weeks of calling each credit union, filing a police report, and changing all of my passwords.

Thankfully, it was just wrong reporting with the same name, so all of the credit unions cleared my name. My score went back up in two months.
