Ariana Grande has told how she suffered "wild dizzy spells" and felt "upside down" for months in the wake of the Manchester Arena bombing.
The pop star had just finished performing on stage in Manchester on May 22 2017 when a suicide bomber detonated an explosive device, killing 22 people.
She told Elle magazine: "When I got home from tour, I had really wild dizzy spells, this feeling like I couldn't breathe.
"I would be in a good mood, fine and happy, and they would hit me out of nowhere.
"I've always had anxiety, but it had never been physical before.
"There were a couple of months straight where I felt so upside down."
The 25 year old returned to Manchester for the One Love benefit concert.
Discussing performing after the attack, she said: "Why would I second guess getting on a stage and being there for them?
The singer recently revealed a tattoo tribute to the victims of the bombing.
