Here, let me help you a bit. You're a Roman Catholic, but not necessarily a Christian. Don't confuse the two. There are some RC's who are also Christians despite what their pagan system teaches, but anyone who believes that Mary is the Mother of Yahweh is no Christian.
Yahweh, aka God the Father, is not the same as Jesus, aka God the Son. They, along with the Holy Spirit, make up the Trinity but Mary is NOT the mother of the Trinity. She carried and gave birth to Jesus, but she did not create Him, which is what the title "Mother of God" implies.
I would highly suggest that those of you caught in this idolatry repent and ask Jesus to forgive you for inferring that He was lying when He said "Before Abraham was, I am."
Jhn 8:56-59 KJV -  Your father Abraham rejoiced to see my day: and he saw [it], and was glad.  Then said the Jews unto him, Thou art not yet fifty years old, and hast thou seen Abraham?  Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.  Then took they up stones to cast at him: but Jesus hid himself, and went out of the temple, going through the midst of them, and so passed by.
Hard to be the Mother of someone who's older than you.
No Catholic believes that Mary is the mother of God the Father, but every Catholic and every real Christian believes that Mary is the mother of God the Son. "The Word was made flesh." At this point, the Word (second person of the Trinity) acquired a human mother.
The God-Man Jesus is inseparable from God the Son. To believe otherwise is condemned heresy.
