Demi Moore is looking back at the struggles of her life and career.

On Monday, the 56-year-old actress sat down for a one-on-one interview with Diane Sawyer on “Good Morning America”.

In the interview, Moore opens up about her difficult childhood, as well as the substance abuse issues and sexism she faced early in her career.

Both of Moore’s parents battled alcoholism; her mother attempted suicide when Moore was 12 years old.

Asked if that was the only time her mother attempted to take her own life, Moore said, “No, there were many, many times. My childhood was done. Yeah, life-changing moment.”

After her father abandoned her family, Moore was left to look after her mother. When she was 15, Moore was raped by an older man in her apartment, who also gave her mom $500.

“I think in my deep heart, no,” Moore said when asked if she felt she had been prostituted by her mother. “I don’t think it was a straightforward transaction. But she still did give him the access and put me in harm’s way.”

Entering Hollywood as a young woman, Moore calmed her fears with drugs and alcohol.

“I don’t have an off switch. I don’t have the thing that says this is enough,” she said, also adding that after going to rehab she has been sober for 20 years.

The actress also discussed her collapse at a party after her 2011 split from Ashton Kutcher, prompting her to go back to rehab.

“I guess the fundamental question that came forward for me was, ‘How did I get here?’ I mean, from where I started to what I’ve experienced, where I’ve been, how did I get here?” she said. “I lost me. I think the thing, if I were to look back, I would say, I blinded myself and I lost myself.”

Moore also recalled some of her iconic roles, including her part in “A Few Good Men”, revealing one sexist experience she faced.

“The studio executive said if there wasn’t going to be a sex scene in ‘A Few Good Men’ then why was she in it?” she said.

That didn’t stop her from eventually becoming the highest-paid actress in Hollywood at the time.

“Why shouldn’t I?” Moore said of the achievement. “Why shouldn’t all women be paid equal to the quality of the work they are doing?”
