What is the difference between counselling and psychotherapy.

Counselling refers to short term therapy which involves the need for support after you have experienced some minor symptoms in reaction to a short term or one-off situational event.
 
Psychotherapy refers to the need for on-going/longer term support due to a history of mental illness, or events which led individuals to experience chronic psychological or behavioural symptoms
