Ariana Grande has penned a heartfelt letter to her fans after she was seen crying on stage while performing during her Sweetener world tour.
In the post, the 26-year-old said: "If you too are hurting, you can push through and are not alone."
She also thanked her fans for accepting her "humanness", saying she sometimes cried a lot because she was touring at a time in her life when she was "still processing a lot".
"Ariana has had a particularly tough time of late and will be feeling emotionally and physically drained, but like a lot of hard working and conscientious performers, she feels she has a responsibility not to let her fans down, and this is important to her ultimate well-being," she said.
She continued: "Understanding and accepting that while she may struggle to contain her emotions during the pressure of a performance, releasing her emotions during these overwhelming moments are part of the process of recovery and along with the enduring support of her family, friends and fans, she will get through this in due course."
Agents have said it is best to help artists who are going through a tough time by creating a peaceful vibe.
"The whole team would support the artist: manager, tour manager, etc.
"The morning after the show, we would sit down together with the artist to discuss what and why that happened."
He added: "If it is something personal related, then I would avoid additional stress and try keep the artist on a peaceful vibe to focus on her next live performance.
"Maybe a sauna or a tour of the city.
"Then ask if they're up for continuing the tour.
"There’s nothing bad with re-scheduling some dates, health (and mental health) comes first!"
In the since deleted post, the singer thanked her fans and said she was grateful for working with the best musicians and dancers in the world.
She said: "I feel everything very intensely and have committed to doing this tour during a time in my life when I'm still processing a lot ... so sometimes I cry a lot!"
Grande said she wrote the message "because I'm grateful and because I want you to know that if you too are hurting, you can push through and are not alone".
She added: "It is hard to balance taking care of the people around you, doing your job, and healing/ taking care of yourself at the same time... but I want you to know, you aren't alone and I think you're doing great.
Many fans have also expressed concern for the singer, with some even suggesting she should postpone tour dates.
The Sweetener World Tour began in Albany, New York, in March.
Grande is set to perform in the UK and Ireland later this year, with dates in London, Birmingham, Glasgow, Sheffield and Dublin planned.
