Cognitive therapy is based on the concept that the way we think about things affects how we feel which also affects what we do. It helps you change how you think and behave.
Cognitive therapy is much more concerned with the present than the past.
Cognitive therapy is also called cognitive behavioural therapy.
Although cognitive therapy is a therapy which involves working with a therapist to overcome problems, it can also be used as a form of self help to greatly improve how we feel.
