On Monday, the singer participated in a trend in which followers ask people to share a photo in response to a question.
Halsey was asked to post a photo with her at the “lowest point” and shared a now-erased image meant to show her struggle with an eating disorder.
She later wrote an apology on Twitter.
“I’m very sorry that I posted a photo of myself depicting my fight with ED without a sufficiently trigger warning,” the tweet read. “I was very nervous to post and I didn’t think correctly. I had positive intentions. I would never want to hurt someone who shares my struggle.”
She added: “However, I will disconnect now, because this has become something that I am not emotionally equipped to manage at the moment. I hope it is fine”.
Last year, Halsey opened up about mental health and life with bipolar disorder.
