I got this from Wikipedia:

"The British Association of Art Therapists defines art therapy as:

...a form of psychotherapy that uses art media as its primary mode of communication. It is practised by qualified, registered Art Therapists who work with children, young people, adults and the elderly.[4] Clients who can use art therapy may have a wide range of difficulties, disabilities or diagnoses. These include, for example, emotional, behavioral or mental health problems, learning or physical disabilities, life-limiting conditions, brain-injury or neurological conditions and physical illness. Art therapy may be provided for groups, or for individuals, depending on clients’ needs. It is not a recreational activity or an art lesson, although the sessions can be enjoyable. Clients do not need to have any previous experience or expertise in art."

It's a purposeful activity. Not just for enjoyment. I hope you can look into this.
