twitter account problem...?

[:-)]

so, I have this old account that I want to get rid of (because it has embarrassing things -_-''), I haven't used it in like three years and I can't remember the email nor the password (I spent I don't know how long trying to remember but it's not working). I went through the twitter help page and it says they can't help if the person doesn't remember both email and password (which I understand because of hacking and stuff) but I think there was also something that said they might delete non used accounts? but obviously they haven't deleted that one.
what do I do?
