facebook is so confusing how can I disable my account?

Permanently delete your account:

Permanently deleting your account means you will not ever be able to reactivate or retrieve any of the content or information you've added.

Click the account menu at the top right of any Facebook page
Select Account Settings
Click Security in the left-hand column
Click Deactivate your account

When you deactivate your account, your timeline and all information associated with it disappears from Facebook immediately. People on Facebook will not be able to search for you or view any of your information.

If you’d like to come back to Facebook anytime after you’ve deactivated your account, you can reactivate your account by logging in with your email and password. Your timeline will be restored in its entirety (friends, photos, interests, etc.). Remember that you will need to have access to the login email address for your account in order to reactivate it.
