It does sound like you ended up with a second account. This board is for simcity, no one will be able to help you here, you need to go to the official support page. https://help.ea.com/en/#
I would suggest logging out of this second account and trying to log in to your regular account again. You might need to reset your password for your "real" account. If all else fails, try the "contact us" page https://help.ea.com/en/contact-us/ Choose Origin, and go from there. Good luck
