You are probably have “deactivating” your account in mind as deletion. Facebook won’t delete everything you have done just like that, they want you to stay as much as they possibly can.
When you deactivate your account, you are doing just that: deactivating it, not deleting it. Even after 2 or 3 months, you can probably log back on. A deactivated account doesn’t go anywhere until about three or four months, maybe more
Now if you want to delete it go here:
https://www.facebook.com/help/contact.php?show_form=delete_account
This will take you through the steps of deletion, and before it is delete it, you mustn’t log in in the 14-day period, you know in case you change your mind (which is what facebook wants) then it won’t be deleted
Hope that helps
