Skilling's charity, The Broken Movement, aims to raise awareness around mental health and preventing suicide through affirmative action.
He said it was designed to help people like him.
Skilling was 19 when he was jailed for nine years for wounding with intent to cause grievous bodily harm. After seven years in jail and a stint at Odyssey House, a rehabilitation service in Christchurch, he was "a changed man".
His own mental health issues had driven him to start The Broken Movement. He had struggled to receive help from conventional psychologists when he was growing up.
"I couldn't relate to them," he said.
"I would ask them, 'have you been molested? Have you stabbed someone? Have you been stabbed? Have you committed crimes?' They would say no, and I would ask, 'Well, why am I talking to you?'"
Skilling said although mental health professionals were needed, he hoped his approach would provide a unique perspective to connect with people.
"When you've got a leak at home, do you call a painter? No, you call a plumber. When you want to pull someone out of that life, you call someone with experience and knowledge. They can relate to them, they have the knowledge to speak to them. Stories to share, an emotional connection."
The Broken Movement would have a presence at community events, support similar organisations, provide financial support to individuals needing mental health services and create educational opportunities through qualified training.
Skilling hoped to put on more events like the one at the Transitional Cathedral last year, where a range of guest speakers shared stories related to mental health.
He was keen to expand the trust to help ex-prisoners.
"It's hard to survive in the world when you get out. You come from a world you know into a world that you don't know, where you're persecuted. It's easy to slip back into old habits. Humans are habitual creatures."
