Jesy formally quit in December after a few weeks of absence, while Sweet Melody went on to become the band’s fifth UK number one single in early January.
Speaking to Cosmopolitan – in an interview in which she declines to comment on her current relationship with the other girls – Jesy reflected on that particular shooting day.
“The last music video we did was the breaking point,” she said. “We’d been in lockdown, and [that had been] the first time I could have a break and be at home around people that I love. It was the happiest I’d ever felt, and I didn’t realise that until I went back to work.
“I immediately became a different person. I had anxiety.”
She added: “I’d been in lockdown, and I’d put on a bit of weight but I didn’t care. And [then] they said, ‘You’ve got a music video in a couple of weeks,’ and I just panicked. I went on this extreme diet, with bloody shakes, and tried to eat as little as possible.
“On the day of the Sweet Melody video I had a panic attack on set because I didn’t look how I wanted to look and I found it so hard to just be happy and enjoy myself. I looked at the other three and they were having the time of their life.
“I get so jealous, because I want to feel like that and enjoy it, because music is my passion. To have this dream and not be enjoying it because of what I look like, I knew wasn’t normal.”
Presumably referring to the body-morphing bit with Jade, Perrie and Leigh-Anne, she said: “There’s a scene in Sweet Melody I’m not in, because that’s when I had a panic attack and broke down.
“I was like, ‘I just want to go home.’ I was sobbing in the dressing room.
“Someone really close to me said, ‘This has got to stop. You can’t keep doing this to yourself. You’re going to end up where you were before.'”
Calling that day the ‘pinnacle point’, she reflected: “It wasn’t nice for the other three to be around someone who didn’t want to be there. So I took a break.
“I went through a really dark time after the music video. My mum said, ‘This has got to stop now. I have seen you suffer too much. This has been 10 years of your life.'”
