Awww SarcasticSally I am sorry, I hope you change your mind. If you really want to leave go to http://www.ask.com/settings?settingType=account and scroll to the bottom of the page, there is a button that says Delete Account, just click it, but remember it is permanent, we can not restore the account if you do this. I hope you decide to stay.
Take yourself off Ask for a period of time. You can restrict yourself, it's not easy, but it's better than leaving us all. Just leave it lie dormant for a while, then come back when you feel like you're in control.
