Psychology, Psychiatry, Counselling and Psychotherapy.
It can be confusing to understand these different terms. I suggest you do a bit of research if you are confused, but as a rule of thumb:
Psychology and Psychiatry are mainly concerned with defining and diagnosing a difficulty, usually serious mental health problems, in order to enable an appropriate treatment. Some Psychologists and Psychiatrists also have training and qualifications to practice counselling and psychotherapy.
Counselling and Psychotherapy: 'Counselling and psychotherapy are umbrella terms that cover a range of talking therapies. They are delivered by trained practitioners who work with people over a short or long term to help them bring about effective change or enhance their wellbeing.' As defined by the British Association for Counselling and Psychotherapy (BACP) website. Psychoanalysis is another term we often come across and this too is a talking therapy and is usually a long term commitment to treatment and the analysis of one's life focusing on past experiences and how they impact on the present.
