Robbie Williams claims he has a "disease in his head" that wants to "kill" him.
The Candy hitmaker - who believes he has come close to death many times before - has admitted he's terrified to be left alone because he's likely to "sabotage" his own life but sometimes his battle with mental health actually helps him get up on stage.
He's quoted by The Sun newspaper as saying: "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.
"Sometimes it overwhelms me and sometimes it's a tool I need to get on stage. Sometimes I live in bliss and it's wonderful.
"But most of the time I'm human - having a human experience, trying to deal with the trials and tribulations of what goes on between my ears."
