‘Psychotherapy’ and ‘Counselling’ are terms that are used to describe very similar practices with the similar goals of relieving psychological symptoms and teaching the tools necessary to live emotionally and physically fulfilled lives.
‘Counselling’ is more often used to describe a shorter process concentrating focussing often on a specific psychological symptom.
‘Psychotherapy’ is generally a longer term treatment which focuses more on gaining insight into the underlying causes of emotional problems. Its focus is on changing the patients perspective on how they exist in the world rather than specific problems.
Whilst a psychotherapist is qualified to provide counselling, a counsellor may not possess the necessary training and skills to provide psychotherapy.
