Many resources exist for sufferers of major depression. Yet millions struggle with less severe mood states that may not be as debilitating, but still drain the joy out of life. Renowned cognitive-behavioral therapist David A. Clark has a clear message for those who feel stuck in the doldrums: there are doable steps they can take to feel better. This book's 80 effective self-help strategies are anchored in the latest scientific knowledge on emotion regulation and mood management. Readers learn why attempts to bury or ignore painful emotions usually fail--and gain practical tools for nipping negativity in the bud, making unhappiness less overwhelming, defusing self-criticism and rumination, and feeling more confident and hopeful every day. David A. Clark is a professor of psychology at the University of New Brunswick. He is the author of The Anxiety and Worry Workbook and Overcoming Obsessive Thoughts.
