The Christian sportsman who lost his world championship belts after a well publicised breakdown is back in the ring this weekend taking on Germany's Tom Schwarz in Las Vegas.
"I'm only human so I do have good days and bad days," he said in an interview with YouTube channel IFLTV. "I'm maintaining through training...the good outweighs the bad so I've got to be happy."
Fury, who often speaks about his faith, won praise for overcoming depression after his belts were taken off him.
He returned to action last year and drew with world champion Deontay Wilder rising from the canvas after being knocked down - something he credited to divine intervention.
The boxer has been opening up about his latest mental health battle and how his quiet times with God keep him on track.
"OCD is tough...the slightest things bug me," he said. "First thing I do in the morning is I go onto my Bible app and I read the verse of the day and it gives me a count on the side so it tells me how many days I've done it in a row without missing one. If you miss a day it goes back to zero and that [annoys] me."
Fury says he's learnt how to deal with his OCD and is aided by his family who understand his situation.
