Cognitive behavioural therapy (CBT) is a talking therapy that helps you understand the links between thoughts, feelings and behaviour. This allows you to manage your problems by helping you change the way you think and behave.
CBT doesn't remove your problems, but helps you manage them in a more effective way. It encourages you to examine how your actions and thoughts can affect how you feel.
It's based on the idea that the way you think about a situation affects how you feel and act. In turn, your actions influence the way you think and feel. It's therefore necessary to change both thinking (cognition) and action (behaviour) at the same time.
CBT is an active therapy, and you'll be expected to work on your problems between sessions, trying out different ways of thinking and acting, as agreed with your therapist. The aim is for you to develop the skills to become your own therapist.
