Discernment of one's vocation can be so difficult. I encourage you to continue to pray, especially in front of the Blessed Sacrament, and to really listen to what God has to tell you. Maybe you are not called to the priesthood, but you just feel you should become a priest in order to please God. Well, marriage is also a sacrament of the highest order. Maybe God wishes you to marry, be open to life and have children, be a wonderful father and perhaps become a deacon in your church. Other thing I think you must do is discuss your strivings toward discernment with at least one priest, maybe a few. I am praying very hard for you to make the decision that God has already willed for you. I pray for you in the name of Jesus of Nazareth. Amen and amen.
