Cant log in to my account.

Hello,
I have a problem to connect to my account . When im trying to log in im requested to enter authentication key, which i cant get since i have other google account , i cant access the one i have the two factor authentication made on . Also i dont know the email i registered my account it was so long ago. But its my account. So i wonder is there any other way to redeem it ? Maybe some question i need to answer for GM to prove its mine? Also there is donation made in my name ... help !
