I strongly recommend the book Feeling Good by David Burns. I even recommend it to people who are not depressed. https://www.amazon.com/Feeling-Good-New-Mood-Therapy/dp/0380810336 https://www.amazon.com/Feeling-Good-New-Mood-Therapy/dp/0380... It describes how depression is often caused by cognitive distortions that somehow cause us to believe that our lives aren't worth living. As a simple example, a depressed person might call a friend, but the friend doesn't return the call immediately, and so the depression patient concludes that the friend doesn't actually care. This is a pure hallucination caused by depression; there are 1000s of reasons why the friend might not have responded immediately. Furthermore, even in the unlikely event that the negative conclusion was true, and the friend doesn't care about the patient, that doesn't mean very much. Maybe the friend is actually pretentious, or is trying to climb the social ladder, or is a political zealot who can't tolerate people with different opinions - all reasons why the patient is better off looking for new friends anyway.
