"It's me telling my story of online trolling, and the online trolling that I suffered in the first five years of Little Mix."
Jesy goes on to explain how in 2011, when she, Jade Thirlwall, Perrie Edwards and Leigh-Anne Pinnock were put into the girl group on X-Factor, they were all told they had to have social media.
"The whole world had an opinion on me, and they weren't good ones," she continued.
On the screen, Jesy shows real-life comments that she once received, including being fat-shamed, called an attention seeker, and even going as far as telling her to take her own life.
"I was known as the fat, ugly one. It literally consumed every part of me."
Band member Jade weighed in, recounting how "You just had to sort of watch this amazing funny girl sort of become a bit like a broken doll it was horrible."
Jesy said that it all lead her to an incident where she attempted suicide in November of 2013.
Thankfully, her boyfriend at the time saved her an called an ambulance.
"I just remember thinking, 'I just need this to go away, I’m going to end this,'" the singer explained to The Sun.
Thankfully, Jesy is much better now and on a path to have her story heard, as a way to help others.
"I think it's important now because social media is such a huge part of everyone's lives like you can say one nasty comment and think they're not gonna see it or it doesn't mean anything to you... but it does. It affects people massively," she explains.
"I wanted to make it [the documentary] so that people know if you talk to people and you get the right help you will be able to feel better again one day," Jesy shares.
Jesy isn't the only member of the band that has opened up about major struggles she has faced.
She revealed it all started when she was 13 years old, discussing that her experience with bullies and a particular death in the family lead her to lose a dramatic amount of weight and be hospitalised.
"My periods stopped and things were getting out of control but I don't think I really cared about what was happening to me," she admitted. "I felt so depressed at the time that I just wanted to waste away and disappear."
