Ricky Hatton admits that the rollercoaster ride that almost saw him take his own life began after his loss to Floyd Mayweather.
The former two-weight world champion revealed that his "ups and downs" started after that memorable night in Las Vegas, in December 2007.
Hatton, who split with trainer Billy Graham after one more fight and no longer talks to his own parents either, made it clear that although the 10th-round knockout was not the end of his career, it was too much to handle.
"People who don't know me would just say 'it was Floyd Mayweather, don't worry about it'," he told Ringside Special.
"I got the biggest pay-day of my career, I was fighting the best pound-for-pound fighter in the world but I went there thinking I could win.
"It was well-documented that I had problems with depression, drink and drugs, suicide and all those things. It's a culmination of things that you end up wanting to take your own life but the start was Mayweather."
Hatton happily recalled the high points in a fantastic career that saw him take an estimated 30,000 fans to Las Vegas, box in front of 58,000 Manchester fans on his comeback and became a "world champion that was one of us".
Yet the 36-year-old, who is now a trainer and promoter, could not hide the fact that for every success, there was a real low.
'The Hitman' went through a rollercoaster ride that saw him fulfil a dream and beat Kostya Tszyu to become a world champion in 2005, yet then have to deal with drink and drugs away from the ring.
"I came back against Juan Lazcano, which was fantastic; City of Manchester Stadium, 58,000 fans and me a big City fan so... brilliant," he said.
"But my performance wasn't great and a lot of people were telling me to retire.
"I parted company with Billy Graham which was obviously very hard. I just thought if I am going to continue, Billy's injures were so bad... I needed a trainer that was fully functional.
"I parted with Billy but he didn't share the enthusiasm, so I fell out with Billy. I was down after the Mayweather fight, then I had the Lazcano fight so I was up, then I was down, falling out with Billy, then up again when I fought Paulie Malignaggi.
"I think I put in my best performance since Tszyu - and many people said I was getting back to my best.
"But then I got [Manny] Pacquiao and got destroyed, so my frame of mind was going up and down, up and down and that all accumulated in falling out with my parents.
"Then that was where the suicide came into it. I didn't really care where I was going."
