Doubts

I have been having doubts about my vocation. I mean i know its a long process to discern one's vocation and I am having serious doubts. I have been seriously thinking about what I am going to give up if I decide to enter the religious life. I will give up any chance to get married and have a family. I guess what I am going through what St. John of the Cross calls a "Dark Night of the Soul." I know some of the great saints of the church like St. John of the Cross, St Theresa of Avila, and Blessed Mother Teresa. I feel like I am in good company when it comes to doubts on my vocation.
