Don't take your anger and fustrations out on God. Instead try to understand it was not your fault what happened. Sometimes members of churches take upon themselves to do things, such as sending you away, when they really don't have the power to do so. They are the kind of people that give good Christian folks a bad name. I would say to try and find another church, or go back to that one if you want to be there and speak with the pastor. If the pastor is not supportive to your need, then that church in my opinion is not worthy of your being there. But never give up on God. Speak to Him and read your Bible, and His words will bring back your strength and courage to believe in Him. I am not saying it will be easy, but if you do these things you will be uplifted and your heart will sing again. I think you will find the words you need to hear in the Book of Psalms.
