Do you feel God is calling you to serve Him? If you do, I would encourage you to talk with a priest, deacon, or other religious. Discernment is a slow and careful process requiring prayer and reflection to determine the true source of the calling, the specific calling, and whether you are up to it at your particular age and stage of life. The most important thing is to not disregard or blow it off. While God is most patient; He will call again!
