Cognitive-Behavioral Therapy is a type of psychotherapy that approaches treatment by teaching people how to think differently about problems and emotions. The idea that feelings and behaviors come from our thoughts, not from external events and situations, or from other people, figures prominently in CBT. According to cognitive-behavioral therapy, if we can change our thinking, we can change our emotions and behaviors. Similarly, if we have learned unwanted feelings and ways of thinking, we can unlearn them.
