Cognitive Behavior Therapy (CBT) is a talking therapy. It can help people who are experiencing a wide range of mental health concerns. What people think can affect how they feel and how they behave. This is the basis of CBT.
During times of distress, people often think in ways that are not helpful or rational. Thoughts can become extreme and worsen how a person feels. They may then behave in a way that prolongs their distress. Therapists who utilize CBT, can help clients identify and change their extreme thinking and unhelpful behavior. There is often a major improvement in how a client feels and lives, once skills are developed.
