To moderators: Is my account deleted? The rep number is now 1 . but I can still login. I cannot ask this on meta because $1<5$. Thanks for the comments. The account is scheduled for deletion now.
The drop down to 1 reputation was due to the fact that you were suspended, independent of any discussion of deletion (suspended accounts automatically go down to 1 reputation; I think this was an old hack to remove their privileges).
Since StackExchange has implemented the ability for users to delete their own accounts, we've preferred to go that route over doing deletions by hand, since there should be no question that it was the user's decision. If you have triggered deletion of your account within the last 24 hours, then you are in the 24 hour waiting period described here (How can I delete my account?), and in somewhat less than 24 hours the deletion of your account will be final.
There are alternatives to deletion. In particular, I still have accounts on other stacks that I don't use anymore, but can return to if needed. You might consider editing your profile to indicate you are taking a MathOverflow sabbatical.
I wish you well on your journey. Hopefully our paths will cross again,with amicable results.
