Q: Forgotten iCloud password and not recieving password reset email.

Hi, I have an iPhone 5, iOS 8.1.2.

My iCloud account is an Apple ID that I do not use anymore, yet I can't sign out because I don't remember the password. I also don't remember the security questions.
When I request a password reset, I'm supposed to receive an email, but I'm not finding any, in any mail box, of any of my email accounts.

Please help? I really want to sign out of the iCloud account and deactivate/delete it so I can use my current one.

Thanks. I really appreciate any help.
