Give up email?

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

Okay, I want to 削除 my YouTube account A LOT, but I just can't 削除 my Eメール address!

WHAT DO I DO?!
