November 28, 2015 was an iconic date for the boxing fraternity as well as in the life of Tyson Fury himself.

The British heavyweight ace squared off against Wladimir Klitschko, who was dominating the division at that time for a decade.

Fury made a remarkable comeback into the sport in 2018, but since that night in 2015 in Germany, even though he did the unthinkable and ended Klitschko's 10-year reign at the top, things took a turn for the worse.

The 30-year-old had been battling depression and several mental issues since, which resulted in him relinquishing his unified titles and sidelining himself entirely away from the ring for almost three years.

Fury did one of the most candid interviews recently, when he explained to Mike Tyson in the HotBoxin' Podcast why becoming the heavyweight champion in 2015 brought disaster along with it.

"I suppose I suffered with depression and anxiety my whole life. From being a little boy to being a man," admitted Fury, as per WorldBoxingNews.

"But, I always had a goal of becoming heavyweight champion of the world. It always brought me back out of the darkness to achieve that goal and nothing else mattered. I had a lot of tragedy in my life and a lot of stuff happen.

"All that maybe could have put me off track of becoming heavyweight champ, but I always side-tracked all of that and concentrated on the job in hand. When they said ‘right, you’re going to fight Klitschko for the world championship’ I was like ‘Hmm. When I win, I’m not going to have a goal anymore’."

He revealed that he knew situations would turn into a nightmare soon and gave an insight into his thought process during his preparations for the showcase event.

"So I almost knew going into the fight that I was going to come down. That it was going to be a disaster," added the Brit.

"I was very depressed going into the fight, going into training camps. I knew I was going to beat this guy. But I remember saying to my dad and brothers ‘Win, lose or draw, I probably won’t fight again after this’.

"They were like ‘You’ve boxed all your life to get to this position and you’re just going to walk away?’ I was like ‘You know what? I’m not feeling it anymore’. But I look back on it and I was very ill going into that fight. I wasn’t well-minded."

The former champion stated that the euphoria of winning and ruling the division lasted just five minutes for him after it ended.

"Goes in there, beats him. For five minutes, I was happy and when I got back into the changing room I was like, ‘IS THIS IT?’

"I’ve won five world title belts, I beat the second-longest reigning heavyweight champion in history, what next?

"I don’t have a purpose anymore, I’m finished,” concluded Fury.

The British boxing star is now back among the elites again, aiming for the top honours one more time, as he prepares to take on Deontay Wilder in a rematch during the first half of 2020.
