Children and youth, who had experienced trauma, often did not want to talk about their experiences.
"The positive thing about art is that there is no right or wrong answer, which is empowering for the children. We use colour, symbols and metaphor to help them externalise the pain and lighten the load," she said.
The children and young people have painted their perspectives of the world around them, concentrating on three themes: worries and concerns; dreams and goals; and emotional resiliency and strengths.
They also identify the one major emotion that brought them to counselling.
Ms O'Halloran said art therapy first came into focus during WWI, when veterans were deeply traumatised by what they had experienced and witnessed.
Nurses and doctors at a loss as to how to help, began providing the soldiers with canvases and paints and noticed a positive emotional shift in their patients, even though they had not received any "therapy" as such.
