Hi Dragonfly. What I think you mean is that you have a Facebook account that uses an email to log in to which you no longer remember the email, much less the password?
The issue you have is with Facebook. They have terrible account recovery service support. It can take a few MONTHS to get them to respond and fix it for you. You will have to show them an ID that matches the name on the account, and then they will probably still ask you for the email you cannot remember. They are impossible to work with because they never actually talk to you. It's all written.
This is the link I found the most help with. Good luck!
