Lewis Capaldi has cancelled all his upcoming work commitments in an effort to "rest and recover" for Glastonbury.
The Scottish hitmaker, 26, took to his social media to share the "difficult message" to his fans.
It comes after Lewis opened up about his mental health struggles and his Tourette's syndrome in his Netflix documentary, How I'm Feeling Now.
Taking to Instagram, the Someone You Loved singer wrote: "Hi everyone, hope you're well. This is a really difficult message and one that hurts me a lot to have to type.
"But I'm really sorry to say that I'm going to have to cancel all commitments from now until I play Glastonbury on June 24th.
"It's been such an incredible time leading into this new album, and seeing all of the support from everyone has been beyond anything I could have ever dreamed of.
"That said, the last few months have been full on both mentally and physically, I haven't been home properly since Christmas and at the moment I'm struggling to get to grips with it all."
He continued: "I need to take a moment to rest and recover, to be at my best and ready for Glastonbury and all of the other incredible shows coming up so that I'm able to continue doing what I love for a long time to come.
"I need to take these three weeks to be Lewis from Glasgow for a bit, spend some time with my family and friends and do normal life things that are an important part of me feeling better. I hope everyone understands.
"I know many of you will have spent money on travel or hotels, which I appreciate more than ever with how difficult things are economically at the moment, so I'm extremely sorry for the impact this will have."
Lewis added: "The fact you're willing to come out and spend your time, money and love on these shows is beyond comprehension and I feel incredibly lucky. I'm getting all the help and support I need from the incredible people around me who I'm so grateful for.
"I take none of this for granted and can't wait to be back doing it again. All my love, Lewis x"
Glastonbury Festival will take place between Wednesday, June 21 2023 and Sunday, June 25 2023, with Lewis set to play on the Saturday.
Just last month, Lewis explained his mental health struggles are a "direct symptom" of his chart-topping career and said he would be prepared to walk away from his job.
Speaking to Rebecca Judd on Apple Music 1 show, the Scotsman said: "I'm managing it better now but I think in 2020 I was kind of glad when we got put in lockdown because I had done my first arena tour in the UK, and we had just done an Australia and Asia tour before that.
"I was in a bad way where I was just having panic attacks every single day on stage and I was just shy."
He continued: "I still haven't quite got there, but it's interesting that this thing that you love to do and you've always wanted to do becomes something that causes you such distress, but such is the modern world."
Lewis went on to disclose that should his mental health continue to deteriorate, he won't hesitate about quitting music and his job.
He said: "If I did another album and my head was scrambled and I felt horrible, right now I'm at a point where I can balance my mental health and how I feel in general.
"Not even just mental health, but the trade-off is worth it.
"I'll take a few panic attacks and my Tourettes and stuff for what's happening, but if it gets to the point where things get worse mentally and I stop kind of looking after myself in that regard, I think that would be a point where I'd be like, 'I'm just not going to do this anymore'."
