TL;DR, my computer broke because I spilled water onto it. I got a new phone recently and my number was changed, so I couldn’t use that to log back in with 2-step verification, and I tried send it to my alternate email instead. It says I have to “wait 24 hours” but I never get the fucking verification email so apparently I have lost my email account and everything attached to it.
When you setup the account they gave you a document with a number of codes that you could print out and save for just a case like this.
If you have tied a credit card to the account there is a chance you could use that to prove ownership and have support get you back in.
