Ariana broke down in tears during her interview with Vogue as the subject moved to Coachella, a festival which held a special memory for her of her ex, Mac Miller, who died of an accidental overdose last year.
"I was always a person who never went to festivals and never went out and had fun like that.
"But the first time I went was to see Malcolm perform, and it was such an incredible experience," Ariana explained.
"I went the second year as well, and I associate, heavily ... it was just kind of a mindf**k, processing how much has happened in such a brief period."
“It’s pretty all-consuming,” she said of her grief over Mac.
“By no means was what we had perfect, but, like, f**k. He was the best person ever, and he didn’t deserve the demons he had. I was the glue for such a long time, and I found myself becoming . . . less and less sticky. The pieces just started to float away.”
She went on to reveal that in November 2018, after Mac's death and after her breakup with ex-fiance Pete Davidson, she realised she needed help.
"I'm a person who's been through a lot and doesn't know what to say about any of it to myself, let alone the world. I see myself onstage as this perfectly polished, great-at-my-job entertainer, and then in situations like this I'm just this little basket-case puddle of figuring it out," she said.
Although the star says she has been open with her fans, in order to drive a conversation around her mental health, there have been times she has kept things to herself.
"I have to be the luckiest girl in the world, and the unluckiest, for sure.
"I'm walking this fine line between healing myself and not letting the things that I've gone through be picked at before I'm ready, and also celebrating the beautiful things that have happened in my life and not feeling scared that they'll be taken away from me because trauma tells me that they will be."
