The Celebrity Big Brother contestant, known for playing "ugly" Sonia Fowler on the BBC soap, slimmed down to a size 10 after repeatedly being branded a "fat bitch" on Twitter.
"Every day I get told I'm going to die or I'm 'a fat bitch' on Twitter," she said. "You've got to be strong - I know lots of actresses who are damaged by it."
She continued: "I only have to look at food and I put weight on. One day I'd fit into my jeans, the next I couldn't pull them up over my thighs.
