just a heads up facebook accounts do not get deleted right away. they sit there for about 90 days while the facebook system works so anytime between you putting in the request and actually deletion (90 days) you can reactivate your facebook page just by logging in. when you log in it will tell you, your account has been reactivated.

also heads up deleting your facebook does not get rid of past posts permanently, any posts or pictures that someone has liked, loved, showed other emoticons for or have commented or shared will remain part of facebook in the way of on your friends timeline because its part of their own history of what they liked and commented on. same with the chat messages. deleting will only delete on your end not on other peoples end.

I think of it like here on psych central when you delete your account here everything you posted remains, just your account is closed.
