Lewis Capaldi had no idea how much his Tourettes and anxiety had been affecting him until he filmed his new Netflix documentary.
The Scottish hitmaker allowed camera crews to have unprecedented access to his life on stage and at home with his family for fans to get to know him on a more personal level.
Lewis, 26, may be used to the life of an A-list celebrity but he received widespread praise for being completely transparent about his struggles and how they affect him on a daily basis.
In one scene, Lewis' family intervene and bring the recording of his second album to a halt as he struggled with his mental health.
Now, Lewis has spoken about his documentary as he explained: "I didn’t realise how much my anxiety and Tourette's was taking over my life until I watched [the footage] back."
He went on to tell The Independent: "When I saw the first draft, it was so depressing, I was surprised I didn't die at the end, I mean, there's always the sequel."
During his documentary, he addressed the viewers and said: "When I have a panic attack, it feels like I'm going insane, completely disconnected from reality.
"I can't breathe, I can't feel my breath going in, I get dizzy, I feel like there's something happening to my head, I'm sweating.
"My whole body starts to do what my shoulder does like pure convulsing, the big thing for me with it is, I'm always going to feel like this now, this is me.
"F**k, this is it, either I feel like I'm going to be stuck like that forever, or I'm going to die."
Lewis went public with his Tourettes diagnosis in 2022 in a bid to prevent people from thinking he was "taking cocaine or something".
He told The Sun: "The truth is, I'm not banging loads of gear down, this isn't drugs, and I've had that accusation on nights out.
"People have asked me directly, 'Are you on drugs, is it cocaine?' and I saw a few tweets knocking around after shows with people saying 'He's on drugs' — and that wasn’t the case.
"If you think I'm going to take drugs and then come out on stage in front of 15,000 and then try to do a show — I mean, obviously, I wait until afterwards... That's a joke."
He also explained that "it's only making music" that causes his tics to be so severe, admitting that he may have to consider quitting the business if they continued to worsen.
