Worship both Jesus and Mary, and God the Father. They are three parts of the Holy Trinity. They are all God, but in Jesus and Mary, God expresses himself through human flesh, and does so in different ways. The manner in which God inhabits the body of Jesus is different from the manner in which he inhabits the body of Mary. The mother of Jesus was filled with God in somewhat the same way the Disciples were filled with God on the Pentecost. God came to Mary in the form of a gray cloud or mist and covered her, filling her womb with his essence. Of course she was already pregnant in the normal way by a man at the time -- probably it was a Roman soldier who got her pregnant -- but God filled that fetus with his essence and made it divine. We know it as the Son of God, Jesus. Mary became the vessel of the Holy Spirit. It is her role to dispense spiritual awakening to those who worship the God-essence within her. It was Mary who formed the intermediate connecting link between pure divinity and humanity. She still fulfils that role as the Queen of Heaven.
