Go into settings and their should be an area for emails or something similar then click change emails or add then delete the other or make the new one a most used

Go to Facebook account settings.
Find a primary email address (new address) and click it.
Then type a password.
And, click "remove" old address.
Type a password again.
After that, when you log in, type your new email address.

Facebook account from the old email??? I am a little confused. It means you want to delete all Facebook emails in your old email address, right?
