I pray directly to God as do all of the original churches. Jesus said to pray. "Our Father..."
The Holy Mother has appeared many times and asked us to pray the Rosary. Why would I not follow her wish?
Her appearances are well documented and studied/challenged by experts.
How do you explain the mysteries of the tilma (The Virgin of Guadalupe) which brought 90 million Mayans to conversion over ten years?
Or the 100,000 witnesses to Our Lady of Fatima?
