I would suggest that you see your doctor first. Sometimes depression has a physical reason and can be fixed with medicine. Secondly please consider talking to your minister. Follow his advice since he seems to have your respect. Thirdly ask him if he knows of voluteer work you can do for a while to make you feel helpful and useful.And last of all you may need to see a counselor to help you find a long term goal for your life and to help you feel like you are moving in a good direction. God bless you.
