Robbie Williams has spoken of his mental health problems, saying: "I've got a disease that wants to kill me."
The 44-year-old singer has a well-documented history of depression and has also fought drug and alcohol abuse.
Quoted in The Sun, he said: "Fortunately and unfortunately, left to my own devices, I'm inclined to sabotage everything.
"I've got a disease that wants to kill me and it's in my head, so I have to guard against that."
Williams added that "sometimes it overwhelms me" and "sometimes I live in bliss and it's wonderful".
"But most of the time I'm . . . trying to deal with the trials and tribulations of what goes on between my ears."
Asked whether the death of George Michael made him reassess his life, he said: "Things I’ve put myself through, I’ve been close to . . . It's like, 'By the grace of God go I'.
"It's been so close so many times. It's been a very similar rollercoaster, yes."
