The Origin of Everyday Moods by Robert E. Thayer has some most useful concepts for mental health recovery. He studied thousands of undergraduate students for about 15 years. He had people keep track of how they felt and how they changed moods and arrived at a notion that there are 4 basic moods: calm energy, tense energy, calm tired and tense tired. Each of these presents a unique opportunity for coping with moods.
