Singer Ariana Grande says she experienced post-traumatic stress disorder following the suicide bomb attack on her Manchester Arena concert in May last year that claimed the lives of 22 people.

The 24-year-old American singer suspended rest of her tour after the May 22 attacks but returned to Manchester in June to host a charity concert to raise 23 million for the bombing victims and their families.

In an interview with British Vogue, the singer has revealed how the bombing affected her. "Yeah, it's a real thing. I know those families and my fans, and everyone there experienced a tremendous amount of it as well. It's hard to talk about because so many people have suffered such severe, tremendous loss… I feel like I shouldn't even be talking about my own experience – like I shouldn't even say anything. I don't think I'll ever know how to talk about it and not cry," she said.

Grande also spoke about anxiety.

"I think a lot of people have anxiety, especially right now. My anxiety has anxiety. I've always had anxiety. I've never really spoken about it because I thought everyone had it, but when I got home from tour (in September 2017) it was the most severe I think it's ever been."

The singer has a worker bee tattoo, the Industrial Revolution-era symbol of Manchester that became a symbol for solidarity in the wake of he arena attack, behind her ear.

Grande's album 'Sweetener' is due for release soon.
