People have counselling when they are emotionally disturbed and feel they need to talk to someone about their problems. They may be sent to a counsellor by their GP or another professional who recognises that they need more time to resolve their difficulties. Typically the majority of people who go for counselling are suffering from a combination of the following: stress overload, depression, an anxiety disorder, an addiction, or anger. ... It follows that a good counselling course equips its students with an understanding of the psychobiology of emotional disorders and the best knowledge of how to go about bringing a beneficial change in the person as quickly as possible.
