If you are depressed it isn't your fault.
Oppression causes depressions. There is an aerodynamic action we can live in. Eternal security protects the mind. Being given Christ's righteousness protects our heart and vital organs. Faith can block all the fiery darts that would cut us off from our supply. Don't blame yourself. Don't blame anyone. The night is dark but the dawn will come. Get help for your body if that is needed but your soul needs God's sunshine to win this battle. You are a precious needed human being. You are important. God loves you in a special way... please don't blame yourself... see yourself through God's eyes and sometime soon you will soar again.
