You sound like a bubblegum snapping teenage girl, so this reply may "so not" reach you. But for the record, Catholics do not worship Mary, the word is 'devotion'. Catholics 'venerate' Mary because God chose her from all time to bear His only Son and hence carry Salvation into the world.
Throughout the ages Mary has been called "The Ark of the New Covenant". The ancient Byzantine-rite Church has always venerated Mary as the "Theotokis", (God-bearer). The Byzantine liturgy is among the most ancient liturgies in Christianity.
The earliest Christians venerated the Virgin Mary with frescos of her that were discovered in the ancient Catacombs in Rome that date back to the late ist century/early 2nd century.
The Blesed Virgin Mary revealed to us in the Bible "from henceforth all generations shall call me blessed", (Luke 1:48). Do you call her blessed?
I call her blessed.
I don't call her a co-mediatrix.
