Do you remember your email address? If you do, you can recover it back.
E.g. Gmail: Type in your email > click forgot password > enter a pass you remembered or anything > you'll receive a code from your phone -if your phone is still active then use this option; else click another option and find an option where you can receive a verification code(new email/email you remembered).
After you've done the last step... Login to your new email, and check if you've received the verification code (copy & paste the code). And there you go, you can change your password, and will be successfully recovered.
Fgunz.net > Click 'forgot password' > type in your email (the one you recovered) click recover and receive a recovery message on your gmail.
P.S. For me it's better to recover your email, so next time when this happens again, you can solve it on your own and can share/teach your friends.
