Replying to Youtube Help

Ok, So I was creating a new Youtube account (I have one already, I want one joke one, and one real one.) I was super stoked to get the username I wanted but once I had already filled out some of the info, I accidentally pressed backspace and the browser went back a page. Now I tried to just click the create account button again, but the username had been taken...by me. I have no fucking clue how to get back to that page or get my username back or finish creating the account. And contacting youtube is fucking impossible.

Does anyone have any ideas?
