Now that it’s been just over a year since the bomb attack happened at Ariana Grande’s show in Manchester last May, the Florida native has been opening up about the experience and what she went through in its aftermath.

In a new interview with British Vogue, Grande shared that she has endured post-traumatic stress disorder (PTSD) since the attack, but that she feels too uncomfortable speaking on her battle when 22 people were senselessly killed and 59 were injured in Manchester.

“It’s hard to talk about because so many people have suffered such severe, tremendous loss. But, yeah, it’s a real thing,” Grande said, discussing her PTSD.

She also mentioned that she doesn’t think she’ll be able to broach the attack without getting upset. “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. I don’t think I’ll ever know how to talk about it and not cry.”

When the singer had wrapped up her concert on May 22, 2017, a suicide bomber set off an explosive device. In the interview, Grande also revealed that after finishing her 2017 tour, she struggled with acute anxiety, but still went straight into recording her next album.
