I am an idiot - question about email

(Before anything nothing of material value was lost)

I decided to deactivate my account because I didn't like the username I came up with.

Now I'm not able to use that email to make account 2.0.
I wanted to have everything payment related organized on one email address so every transactions is sent there.

In short are emails and usernames permanently blocked when you deactivate an account?
