One of your best friends feels that he fails at everything he does and that his life isn't worth living. When you suggest that he talk to a psychotherapist, your friend responds, "Talking won't help. The more I talk about myself, the more I think about my problems. The more I think about my problems, the more depressed I get."

Explain why your friend's comment illustrates his need for cognitive therapy. What procedures would a cognitive therapist use to help your friend overcome his negative feelings?
