In an incredibly honest interview with ​British VogueAriana Grande revealed she suffered from post-traumatic stress disorder (PTSD) following the Manchester bombing.

Last May, a suicide bomber detonated an explosive device at one of her concerts, killing 22 people and injuring 59.

“It's hard to talk about because so many people have suffered such severe, tremendous loss. But, yeah, [my PTSD is] a real thing,” she admitted.

She also opened up about the guilt she feels for even discussing her struggles after the attack, sharing, “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.”

After the attack, Ariana returned to Manchester and held a benefit concert which raised $3 million within three hours.

She also shared she got a worker bee tattoo behind her ear last month, in tribute to victims of the Manchester bombing. (The worker bee is one of Manchester's best-known symbols.)

At the end of her most recent music ​video, her first since the attack, ​Ari​ana is shown sitting in the grass with a bee flying near her, which many believe to be another tribute to the Manchester victims. 

“I don't think I'll ever know how to talk about it and not cry,” she confessed.
