How fun is that? what are you selling?  where you forgot your wallet password. generally a ETH wallet provide private key for backup that wallet. and MEW wallet provide a key file. you you want to login your account you must have that file and you have to login your wallet to using your file and password. you just says you will sell your wallet but you didn't mention any details If you haven't mentioned anything here then what do you want to sell? Fucking joke
