Hi moderators, Tashiga here. How do I get my identity back?

Hi, it's Tashiga, I created this new account just to be able to ask this question. I just took a look at my profile and saw it was well outdated. So I edited it and put my new e-mail adress, but I made a mistake typing it and since altering the adress involves getting a new password - sent to the new adress, which doesn't exist since I mistyped it - I no longer can access my account! I don't know my new password, and will never receive it... Anyone knows what I should do? Anyway I can get my account back instead of having to create a new one?
