Spiritual Depression: Its Causes and Its Cure, Dr. Martyn Lloyd-Jones, 1965. Gently but firmly addresses potential causes including inability to receive forgiveness for all sins, not moving beyond past failures, seeing only bad and not good, not recognizing false teaching, lack of faith, not seeing trials correctly, etc. This older book stays centered on Biblical solutions. Very helpful.

Excerpt from the Tract
Leviticus 19:16 Thou shalt not go up and down as a talebearer among thy people: neither shalt thou stand against the blood of thy neighbor: I am the LORD.
The definition of gossip is a person who repeats news or rumors, even murmurings or conversation that hurts other people’s image, when these people are absent and cannot defend themselves. It is a cowardly form to speak about others behind their backs (or being absent) in order to discover something (true or false) about them that they would not say in front of that person to their face because it is insulting or would humiliate the person. Gossip is an attack against the person they are talking about.
