Psychotherapy and Counselling are often interchangeable terms used to define talking therapies working with individuals who are struggling with certain aspects of life.
Psychotherapy has traditionally been a name given to a type of therapy that focuses on more deep-rooted issues often with origins of childhood. During psychotherapy unhelpful behavioural patterns and thinking styles are often explored with the focus on understanding the cause and then working through the issues from the past in order to make changes in the present.
Psychotherapy is often a longer term therapy than counselling. A psychotherapist has often had more intensive and longer training than a counsellor but in practice there is very little difference between the two and definitions are becoming quite blurred.
