Give up email?

I want to 删除 my YouTube account because I feel that I'm not 安全 anymore. But I figured that the only way to do that was to also 删除 my account on:
Web History
谷歌 Talk
YouTube
and GMAIL?!

Okay, I want to 删除 my YouTube account A LOT, but I just can't 删除 my 电子邮箱 address!

WHAT DO I DO?!
