The 38-year-old disappeared from home last month and sparked a missing persons appeal before he was found safe and well in Liverpool.
The former chairman of the Professional Footballers’ Association has campaigned to raise awareness of mental health issues and launched the Clarke Carlisle Foundation for Dual Diagnosis – a condition that has been described as “mental health problems co-occurring with drug or alcohol abuse”.
The former Burnley defender described his recent turmoil saying he had been “strolling around” Liverpool and was “headstrong set on the most convenient way to kill myself” when a passing stranger intervened.
“I didn’t know what was going on,” said Carlisle during an interview on BBC 5 live. “I didn’t have my phone with me; obviously I was lurking in the shadows, looking for, you know, this place and that place, trying to mind my own business.
“This car pulled up while I was sat in a park and a guy came over and said, ‘Oh, I thought it was you. You know your family is looking for you?’ and I guessed as much but I didn’t know the extent of how far it had gone.
“This guy, sadly for him, his friend had killed himself a few days earlier and he said ‘I thought this was you and I could not go by not checking’ because he’d heard the state that I was in and he just wanted to help.
“And I didn’t want his help, I didn’t want his help sat in the park, but this guy came and sat next to me and he hugged me and he cried on my shoulder, just urging me to get in touch with my family.”
The man called Carlisle’s pregnant wife, Carrie, and put Carlisle on the phone.
Mrs Carlisle said: “I heard his voice and it was literally like the best moment of my life because I thought I’d never hear from him again and this wonderful gentleman stayed with him.
“It’s horrifying to realise that you’ve been engaging not with your husband but with an illness that manipulates the individual to the point where they feel they’re a burden.
“We’re surrounded by love all the time but what I didn’t know is that he couldn’t feel that love. It was like he was living in a glass box.
“I judged a crisis by my own standards. What I thought was minor was literally the end of the world for Clarke and if I could go back I would stop using my own mental framework as a reference.”
Father-of-three Carlisle spent three weeks in hospital and is now recovering at home.
In December 2014 he tried to take his own life when he jumped into the path of a 12-ton lorry on the A64 near York.
