I need to unlock my icloud account!!!

I need help unlocking my icloud account that I locked a few years ago due to some issues I had back then. And the thing is, I only have two options to unlock it(they send an email with instructions on how to unlock it or answer security questions that I apparently put back then)and I no longer have that email available and also forgot the answers to my security questions. I do remember my Apple ID and passcode, but it doesn´t seem like enough. Please help, I need to do this ASAP.
