Former heavyweight champion Tyson Fury has revealed that his weekly routine causes him to have suicidal thoughts every Sunday, ahead of his rematch against Deontay Wilder.

Fury has opened up on the dark thoughts which occupy his mind ahead of his February 22 rematch against Deontay Wilder, admitting that he feels "absolutely suicidal" every Sunday and believes that he will be "dead within a year" if he were to quit his boxing career.

The 31-year-old has constantly battled against mental health issues over the recent years, suffering from depression following his title win over Wladimir Klitschko in 2015, experiencing drug and drinking problems and admitting to having thoughts about ending his own life.

Despite his difficulties, Fury has successfully managed to rebound from that dark time after two-and-a-half years out of the ring, and now has his sights set on dethroning Wilder and winning the WBC heavyweight title.

In a very open segment in an interview with Behind the Gloves, as per The Independent, Fury revealed that he still greatly struggles with his mental health when he has nothing to do, after managing to keep himself occupied each Monday to Saturday.'

"I look forward to Saturdays," he explained. "I do a long run in the morning and then I will do something with the kids or whatever I can.

"Then Sunday comes and every Sunday I am absolutely suicidal - every single Sunday whether I am in camp or I am at home.

"It is like the world has ended and I just wanna not live anymore.

"That is Sunday. And then I go to bed on a Sunday night thinking yeah, Monday is tomorrow, I can start my stuff again. Back to the gym, back to the coffee shop, back to the lunch, back to the kids.

"That is the way I live. It is routine that is keeping me alive and keeping me going.

"If I give up the gym I will be dead within a year that is for sure."

Fury has also explained that in 2016 he was suffering from "personal demons" as he plunged into a downward spiral due to cocaine use and drinking daily, while also putting on weight which he described as leaving him "fat as a pig."

'The Gypsy King' has long been an advocate for promoting the awareness of mental health issues, not too long ago revealing that he'd talked a man out of killing himself by taking him on a run.

In his last match against Wilder, Fury came extremely close to reclaiming his world championship status, when he boxed to a draw after an incredible recovery from a second knockdown in the final round.

His current record still shows him unbeaten at an incredible 29-0-1, so we'll see if the Mancunian can keep his clean sheet going into this rematch.
