The undefeated and charismatic heavyweight from Manchester, England, has openly told us the dark times of his life.

About how he abused alcohol and cocaine, swelled to over 180 kilos and drove his Ferrari for over 300 kilometers per hour against a bridge.

- I've been struggling with depression and anxiety all my life. I was down at the bottom trying to kill myself. It was a really heavy period, but I came back for a reason. To spread the word about mental ill health and show that there is a light at the end of the tunnel. It's going to be good again, Fury told SVT Sport in September.

On his social media, he now talks about an incident last week when a stranger appeared at his door.

- It was a strange experience that has made me stronger. He told me he was going to kill himself, but wanted to talk to me first. We talked and then I took him out on a five kilometer run. It felt like it worked because when he left he seemed happy, says Fury.

And the star comes up with a call:

- Everyone out there suffering from mental ill health, please don't commit suicide. Life gets better, I promise. There is help to get. You can return to the person you have been. Come on, never give up! Continue to travel just like I did in the twelfth round against (Deontay) Wilder.
