“Cognitive behavioural therapy (CBT) is a talking therapy that can help you manage your problems by changing the way you think and behave. It’s most commonly used to treat anxiety and depression, but can be useful for other mental and physical health problems.
CBT is based on the concept that your thoughts, feelings, physical sensations and actions are interconnected, and that negative thoughts and feelings can trap you in a vicious cycle.
CBT aims to help you deal with overwhelming problems in a more positive way by breaking them down into smaller parts. You’re shown how to change these negative patterns to improve the way you feel.”
