" On earth, however, God doesn’t prescribe a happy life. Look at some of the Psalms. They are written by people of great faith, yet they run the emotional gamut. One even ends with “darkness is my closest friend” (Ps. 88:18). When your emotions feel muted or always low, when you are unable to experience the highs and lows you once did, the important question is not “How can I figure out what I have done wrong?” but it is, “Where do I turn—or, to whom do I turn—when I am depressed? "
