Jodie Marsh's mum has admitted her daughter is on the brink of cracking up after her treatment on 'Celebrity Big Brother'.Kris Marsh admits watching her daughter, who was voted off the hit reality show last Friday (13.01.06), being harassed by fellow housemates Michael Barrymore, George Galloway and Pete Burns was extremely difficult for her.Jodie's mum admits the experience has left her daughter emotionally fragile and vulnerable.She said: "Jodie could break. I'm desperately worried about her. It's heartbreaking."Kris thinks Jodie's treatment in the House was even tougher for her because it brought back memories of the horrific bullying she suffered at school.The glamour girl, who broke her nose playing hockey, was tormented at the private Brentwood School for having a crooked nose, and then after having cosmetic surgery to correct the problem, at 15, was bullied further.Kris insists the behaviour of Barrymore and Galloway was no better, telling Britain's Closer magazine: "Almost every day she'd come home in tears. She got called 'Michael Jackson' and 'plastic face'. People would shove her on the stairs and spit in her pencil case."
