All Minds occasionally experience a degree of mood change (sadness, worry, and associated problems like sleep, appetite, interpersonal interactions, etc.). Sometimes those mood issues last longer than two weeks and get in the way of work, school, or family life, or otherwise distress you. When the cycle of negative thinking and self-defeating behavior becomes difficult to break alone, many benefit with additional help. Therapists may use Cognitive Behavioral Therapy, the gold standard approach that increases positive thinking and engaging behaviors to boost mood and break the self-defeating cycle.
