If you are tricked, I think there is no way to get your wallet back. You only have to learn after what you have; you should preserve your account. Or you can contact the 3rd party to keep your bitcoin number
Yes, you cant retrieve what they've stolen from you. So for next time dont trust no one and just be careful on where you put your wallet password. Learn from your mistake, because mistakes is a great teacher. Dont be a fool to be scammed for the second time, if you got scammed again then you didn't learn. I guess that bitcoin is not yours to keep. Just find another thing to invest to.
