Jesy Nelson has been praised for her "inspiring" documentary addressing the impact of online bullying.
Odd One Out, made by BBC Three, aired on Thursday on BBC One and revealed how comments from trolls had led the Little Mix star to attempt suicide.
The 28-year-old, who rose to fame on The X Factor in 2011, spoke of how she became almost "obsessed" with reading negative comments about herself.
Actress Emily Atack tweeted that the film should be shown in schools.
"Show it in schools, tell your mates, watch it," she tweeted. The Only Way Is Essex star Georgia Kousoulou agreed.
Wow #OddOneOut was heartbreaking but amazing! I think this should be shown in all schools and colleges around the world 🙌 .. Jesy you should be so proud of yourself 🙏— Georgia Kousoulou (@MissGeorgiakx) September 12, 2019
This Jesy Nelson documentary needs to be shown in every single school and college up and down the country to show that words can break even the most strongest looking people and ruin so many lives. Just be kind. 🙏🏻 #OddOneOut #LittleMix #JesyNelson pic.twitter.com/GGSzVplpUY— Joe (@JoeSaunders) September 12, 2019
Stacey Dooley described Nelson as a "total star", while EastEnders actress Tilly Keeper praised the singer's bravery, saying her story was "necessary in today's technological and social media crazed climate".

Jesy, you a total star. ✨
To everyone who consistently digs out other people online, your behaviour has such serious consequences.
We all need to make a conscious effort to just be a bit kinder.
I implore you to watch Jesy Nelson’s documentary #OddOneOut— Tilly Keeper (@tillykeeper) September 12, 2019
Brave, inspiring and necessary in today’s technological and social media crazed climate
Reality TV star Charlotte Crosby agreed that Nelson was brave to speak out, and called on social media platforms to do more to stamp out trolls.
Jesy nelson is a brave beautiful women. But sadly she’s not the only one who falls victim to the abuse from troll accounts with no identities. This has gone on for too long now. SORT IT OUT SOCIAL MEDIA WORLD. ✋🏼✋🏼✋🏼✋🏼✋🏼✋🏼— Charlotte Crosby (@Charlottegshore) September 12, 2019

Nelson's Little Mix bandmates told the programme about the toll internet bullies took on the singer. "The three of us didn't know what to do," said Jade Thirlwall. "We just had to watch this amazing, funny girl become a bit like a broken doll. It was horrible."
She added: "I remember feeling really angry. I wanted to just find every single person that had ever said anything horrible to her, look them in the eye and say, 'Look what you've done to this girl.'"
In its review, The Guardian gave the show four stars, calling it "a modern fairytale in reverse".
Critic Rebecca Nicholson wrote: "This raw, candid documentary explores the fallout Nelson faced after winning The X Factor with Little Mix: a relentless barrage of abuse from cyberbullies."
While Nelson's mental health has gradually improved since she deleted Twitter, Leigh-Anne Pinnock from the band said there had been a lasting impact.
"She is a little bit of a nightmare when it comes to video shoots and photo shoots," she said. "It has been a bit hard within the group. People don't realise what bullying and trolling can do to someone. The trolls took away her love for it and her passion. But how does she get that back?"
Nelson announced earlier this year that she was making a documentary exploring body image and mental health because she wanted to "make a change and a difference to other people's lives".
