The fed up actress had been voted in by the public to take part in 'Rodent Run' and from the off it was clear she had had enough.
She told Ant and Dec: ''I'm not feeling this, I have given it 100%, what more can I give?
"I will have a look, obviously I really want to give everything a go and I'm not a quitter at all, but if I think absolutely no I've had enough, then I've had enough."
The trial involved the actress having to get into a giant hamster cage which was divided up into five areas.
The first part of the trial saw Helen Flanagan have to run on a novelty sized hamster wheel for two minutes while meal worms would be dropped onto her head.
Despite the relatively easy challenge and encouragement from Ant and Dec, Helen couldn't bring herself to take part.
As the klaxon sounded for the start of the trial Helen immediately got out of the wheel saying: "I really don't want to this, please let me out, I'm freaking out. I'm really sorry I want to get out now.
She continued: "It's really panicking me and I'm really, really sorry. I don't want to let anyone down its just really freaking me out.

"I don't want to let anyone down, the whole thing is completely freaking me out because it's my fifth trial. I know it's only meal worms, it's really working me up and I don't want to put myself through it and get absolutely terrified. Honestly I'm really scared."
We don't know who to feel most sorry for, the starving celebs or the crew members who have spent months coming up with and building the trials.
Surely the public will see sense and vote someone else in soon?
