Welcome to Android Central! You don't remember your Google account at all? For an Android device, your Google account is probably the single most important piece of information to remember, since so many things are dependent on that. And since you forgot your recovery email account, I don't think you have any other options.
Maybe one possibility -- take out the SIM card and insert it into someone else's phone, then see if you can get that verification code for your Yahoo recovery email.
