I assume that many Catholics have already told you, over the years, that we do not "worship" Mary, we revere her.
Catholics are always correcting that accusation, yet the accusation persists.
Most catholics I’ve seen WORSHIP and PRAY to Mary and other dead ‘saints’. By the way, a saint is a believer in Christ; it’s not a special designation beyond that (but being a Saint is the most magnificent designation in the world).
When you have the power of Christ living inside you, you will realize you do NOT need “help” from the dead and in fact are in breech of God’s commands to not worship or call on the dead.
