I don’t believe that this stops, I believe because it is biblical that departed saints pray for us, but I do not pray to my friends or departed loved ones. I pray to My Father who is in heaven, as My LORD Jesus taught me. I do not go through a friend to get my God. I cry out to God when I am in need of healing. I pray for people they pray for me, but I have NEVER prayed asking my friend for healing, no I ask God.
What do you think "praying to saints" means? It means exactly that: asking a fellow "saint" to pray to God! God does the healing. Surely you know that.
So you admit to asking others to pray for you... JUST LIKE THE NUN.
She asked a friend, in Heaven, to pray for her.
I recommend this article: Praying to the Saints It goes in depth with Biblical support and explains how it does not contradict Christ's role.
