The 22-year-old former Coronation Street star was filmed having a bit of a meltdown prior to her third trial, the Cruelty Towers challenge.
Footage which will be screened this evening shows her saying: "I need a few minutes. I'm scared. It just makes me want to go home.
"If they're going to keep doing this to me every single day I want to go home. I just really want people to stop voting for me. I'm not happy at all. I don't want to do it."
The task sees Helen having to navigate around a "hotel" whose "guests" include snakes, a crocodile, ostrich and spiders. And The Sun reports spin-off show host Laura Whitmore as revealing that the crew are all getting fed up with Helen's flapping.
She said: "Viewers saw two minutes of Helen doing the trial. But in reality the filming took ages.
"The film I saw was half-an-hour long and that had been seriously edited. She was moaning about everything and kept changing her mind.
"She will be a nightmare if she is voted to do the live trials, because they have to be done to time. She'll just have to be made to do it."
"Ant and Dec have lost patience with her and I think most of the crew hate her since she bailed out of the Bug Burial Trial. Months of preparation, health and safety checks and testing goes into those trials. One lady even has to count every single insect used.
"So to do all that and have Helen walk away after just 10 seconds is annoying."
And Laura even suggested that Flanagan wasn't even serious about quitting.
"Helen was never going to walk off. She was just saying it for someone else to say, 'No, stay.' It was attention-seeking."
