According to the star, "nine out of 10 girls" in the entertainment industry are affected by similar problems.
She went on to say she struggled with feeling like she wasn't "quite enough" and it became a "way of being".
"I was just a child going through a physiological illness and I kind of self-sabotaged because internally I was not well," she explained.
"I didn't know up from down. [I thought] How am I going to be a celebrity and be able to handle all the pressures."
Last week, speaking to 10 News First, the Grease star, 71, and her daughter discussed how Chloe has overcome drug addiction, depression, anorexia and body dysmorphia.
Olivia gushed: "She's doing things I never could have done. I never did anything ambitious as you are doing, darling."
Chloe, whose father is actor Matt Lattanzi, explained how her stint on Dancing With The Stars has been a "rebirth" for her.
"I am having the time of my life, it's like a rebirth," she said, as she explained she hopes her story will inspire others who are suffering mental of physical illnesses.
Proud mum Olivia couldn't hold back her praise for her daughter.
"You just have a natural beauty and grace that is just so wonderful to watch, it just makes me well up," she added.
