Give up email?

I want to xóa my YouTube account because I feel that I'm not an toàn, két an toàn anymore. But I figured that the only way to do that was to also xóa my account on:
Web History
Google Talk
YouTube
and GMAIL?!

Okay, I want to xóa my YouTube account A LOT, but I just can't xóa my email address!

WHAT DO I DO?!
