The actress, who is contracted to stay in the soap until at least 2012, said that while portraying her character is enjoyable, she sometimes struggles with some of Tracy's meaner lines.
"I really like Tracy, as odd as it sounds," she told The Mirror. "There's a real sense of danger with her - she did kill someone after all and you wouldn't want to p*ss her off. You get to say the most ridiculous, vicious things which can be fun. But it can be horrible too. You'd be surprised at how difficult it is sometimes.
"She's said some really hurtful things to Becky about her not being able to have babies, and when her little boy Max was taken into care. I'm a mum myself and I've found it hard to say some of those things.
"They feel like the most spiteful things that would be hurtful to any woman. I'd never dream of saying things like that in my life."
Ford added that she believes Steve McDonald will never love Tracy and wouldn't be with her if they didn't have children together.
