"I was so pleased to see how well Jonny was doing, I had thought about him over the years and had always hoped he was OK," the 31-year-old personal trainer said.
Speaking about the incident, he said: "I didn't feel it was that big a deal, I did what anyone would do. I wasn't trying to fix his problems that day, I just listened. Hand on heart that Jonny is one of the nicest people I have ever met, it's brilliant to see him smiling again.
"We'll definitely stay in touch," he added.
Rethink Mental Illness announced the news on Twitter with a photo of the pair captioned: "We #foundmike! *Huge* thank you to everyone who shared the #findmike campaign, you made THIS happen".
The photo was taken when the men were reunited on Tuesday.
Mr Benjamin, who is now a mental health campaigner, said: "I feel like I've won the lottery - I'm totally elated. It means the world to me to finally have the opportunity to say thank you.
"It's as though I've come full circle and that chapter of my life has now closed. He's such a warm, genuine person - everyone should have a friend like Neil."
Mr Benjamin said he hopes his story will give others struggling with mental illness some encouragement to take Mr Laybourn's lead.
"It really shows how the simple act of listening can be a huge support to someone who struggling with their mental health and we can all learn from that," Mr Benjamin said.
Paul Jenkins, CEO of Rethink Mental Illness said: "The overwhelming public support for Jonny and his search has been incredible. Every single person who shared his appeal has not only helped find 'Mike', but has also helped to open up millions of conversations about mental health.
He continued: "We don't talk about these issues enough, but the more we do, the more we break down the stigma that surrounds them."
