Did you register a recovery email with facebook for this very reason? If your answer was no, then there is nothing anyone can do.
We are CCM.net, and we don't take care of facebook accounts! We can give you a link, but if you have not registered another email, it will do you no good!
We understand that this is too late in this circumstance, but always create IMPORTANT accounts, such as email, and lesser important accounts, such as social media, on a landline workstation. A landline workstation can be laptop on wifi, or a desktop on wifi for that matter. The important thing; the account is created from a WIRED, NON-cellular network.
The provider can offer many ways to recover your account, if you create it in this manner. Always attach a recover email, such as a work, or another email that you will not forget the username and password to (because it SO important)!
After you have attached another email address in case of forgetfulness, now you can attach a mobile device to the account. Now, if you lose, break, or stop having access to your mobile device (non-payment of services), you can still recover your account!
