"I don't think I'll ever know how to talk about it and not cry," the 24-year-old said in an interview with British Vogue about the May 22, 2017 concert bombing.

“It's hard to talk about because so many people have suffered such severe, tremendous loss. But, yeah, it's a real thing,” she said. “I know those families and my fans, and everyone there experienced a tremendous amount of it as well. Time is the biggest thing. I feel like I shouldn't even be talking about my own experience – like I shouldn't even say anything.”

The new issue of British Vogue will be released Friday.

PTSD can develop after an unusually traumatic event, such as violent personal assaults, natural or human-caused disasters, accidents, combat and other forms of violence, according to the National Institutes of Health.

The disorder can significantly trample the ability to function at home, work or socially.

People with the condition often suffer flashbacks of the traumatic events, nightmares and frightening thoughts.

Psychotherapy and medications, commonly antidepressants, are considered the main treatments of PTSD.

According to the NIH, Department of Veteran Affairs and Sidran Institute, PTSD affects approximately 7.7 billion American adults each year. Of the 15-43 percent of girls who experience at least one trauma, 3-15 percent develop PTSD. Of the 14-43 percent of boys who go through at least one traumatic experience, 1-6 percent develop the condition.
