Jesy opens up in the forthcoming BBC documentary, Odd One Out, about how nasty and cruel comments about her looks and weight negatively affected her.
The 28 year old singer has bravely admitted that she used to starve herself for four days after cruel trolls labelled her “fat”, while she also attempted to take her own life during a deep depression.
Jesy’s mum Janice White also speaks on the documentary, as she laments her daughter losing her confidence because of the online abuse she faced.
Janice also says that she prefers her daughter wearing less makeup and showing off her natural beauty, though Jesy has said she enjoys using cosmetic to add to her stunning looks.
In the documentary, the mother-and-daughter duo look back through a photo album and at pictures of Jesy growing up, with Jesy saying her mother would want her to go back to how she previously looked.
Janice says: “Sometimes I want to tell you for your own sake your make-up is looking too much. Like your eyelashes are too long. You don’t need to do that. Natural is the best.
“I wish you could see the way I see you without make-up on because I think you look lovely.”
Janice also said she wishes Jesy didn’t find success on The X Factor in 2011, when Little Mix was formed.
She says: “I always say I wish it was back to normal. I wish I could have life as it was and have my funny little Jes back.
“I am so proud and when I watch her on stage I get excited. I’m the loudest cheerer in the crowd.
“But as much as I love all that, and people must think how can you say that, if I could have my Jes back as she was before I’d change it like that. Not have the X Factor or any of that. Because I miss her.
“I just kind of feel like I’ve lost Jess to social media. Addicted to what people are saying.”
In the documentary, Jesy candidly reveals she attempted suicide after being cruelly trolled online – by people including Katie Hopkins – and labelled as “the fat one” in the band.
Jesy told of how she tried to take her own life in November 2016 after being constantly sent abuse online about her weight and looks – a revelation which left her mother devastated.
The heartbroken mum says: “It was just horrible knowing your child has done that. The worst thing was she lived three minutes walk from me. I was probably in bed and she had done that to herself.
“It’s horrible. And knowing…can we just stop there,” she says as she breaks down in tears.
She adds: “You’re just laying there going to sleep and one of your children is going to kill themselves. I felt like a bad mum really.”
Jesy’s boyfriend, Love Island star Chris Hughes, has praised her for speaking out on how trolls so negatively affected her.
Discussing her documentary on Instragam, Jesy wrote: “Hey guys, I’ve been waiting to share this for such a long time and tomorrow I finally can.
“I haven’t really told anyone what’s in my documentary yet. I think a lot of people are going to be quite shocked. I’ll be posting the official trailer tomorrow morning for #oddoneout keep a look out for clips I’m going to be posting before it airs on BBC One at 9pm on Thursday 12th, and BBC Three online.”
Chris commented on the emotional post, writing: “Well done Jess, you’re an amazing girl, you should forever be proud of yourself and all you’ve come through and achieved.”
Shout Out To My Ex hitmaker Jesy replied to his gushing message: “I love you so much.”
Jesy and Chris, 26, started dating in January, with their relationship going from strength to strength ever since.
Jesy Nelson: The Odd One Out is on BBC Two at 9pm on Thursday 12 September.
