It might behoove you to do a little investigation, and read up on some other appearances of Mary.
Some of them have resulted in many conversions *to* Christianity.
It would probably be far more prudent to say of veneration of Mary (think of sainthood as the Hall of Fame or the All-Star break; only celebrating a life lived in service to Christ rather than throwing a ball around a stadium) "not my cup of tea" rather than making your own ex cathedra pronouncements.
Read or example Romans 14 ..."it is before his own master that he stands or falls, for God is able to make him stand."
I've read the other accounts of apparitions claiming to be Mary. They follow a similar pattern. Their message when examined fully is counter to what is revealed in Scripture.
As a believer in Christ I recognize Mary as the mother of Christ. We count her blessed. She was in need of a Savior as the rest of us for all have sinned.
We do not bow down before her or pray to her though. We are not to have idols of her. That would be in contradiction of the Scriptures.
