Sweet soul, until a few days ago i was fretting and crying my eyes out for my prayers but then i came across Andrew Wommack's ministries. Take a look at that and you will find a new perspective and the answers to your questions. It is the most positive message that God can send to us. Try to go through his words and you will find the difference.
