Ariana Grande has revealed she suffered post-traumatic stress disorder in the aftermath of the Manchester terror attack.

On May 22 last year a terrorist detonated an explosive device as fans were leaving Grande's concert at the Manchester Arena, killing 22 innocent people and injuring more than 500.

Speaking to British Vogue, the 24-year-old singer opened up on how she felt following the incident, and said that the dizziness and anxiety she felt were signs of PTSD.

"I hate ... yeah ... admitting it but it very much is. That's what everyone was telling me. It's hard to talk about because so many people have suffered such severe, tremendous loss.

''But, yeah, it's a real thing. I know those families and my fans, and everyone there experienced a tremendous amount of it as well."

Grande said she is reluctant to open up about her own experiences because of the suffering felt by others, but admitted she struggles to talk about the horrific experiences without breaking down.

"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.''

Following the attack, Grande became an honorary citizen of Manchester and arranged the One Love Manchester benefit concert to raise money for the victims of a terror attack in the city.

Grande recently paid tribute to the victims of the Manchester Arena bomb attack on the first anniversary of the atrocity which took place at the end of one of her concerts in the city. 

In a message on social media, the American singer wrote: "Thinking of you all today and every day. I love you with all of me and am sending you all of the light and warmth I have to offer on this challenging day."
