Well, against all odds, you managed to change your username, which in this case seemed potentially well justified due to placing your email as your username by mistake. The logical options were to do that, delete the account (anonymize), or have you change your email everywhere. I figure that you have not tied that email to your account, in order to reduce risks, and that you'll consider whether it’s worth changing the email per se.
A xMas gift by all means.
Note: You may want to ask people who quoted your OP to consider deleting at least the container, that bears your old username. I've deleted my quote in my prior post on this thread.
