Reality star Paris Hilton is all set to debut her explosive new documentary, "This Is Paris" on Sept. 14 on her YouTube channel.

In the documentary, the successful entrepreneur has revealed many personal details, including the horrific abuse she was subjected to as a teen reality star reveals for the first time the horrific abuse she says she endured as a teen while she was studying at a boarding school in Utah.

In an interview with People, Hilton, 39, talked about the mental, emotional and physical pain she underwent for the 11 months she spent at Provo Canyon School in the late '90s. “But I’m proud of the strong woman I’ve become. People might assume everything in my life came easy to me, but I want to show the world who I truly am,” she said. 

Hilton shared that her strict parents who were fed up with her 17-year-old teen rebellious ways in 2003, sent her away to Provo Canyon School. But she soon realized that of the many boarding schools she has been in, Provo “was going to be worse than anywhere else” as she started facing abuse daily. 

“It was supposed to be a school, but [classes] were not the focus at all,” shared Hilton. “From the moment I woke up until I went to bed, it was all day screaming in my face, yelling at me, continuous torture.”

“The staff would say terrible things. They were constantly making me feel bad about myself and bully me. I think it was their goal to break us down. And they were physically abusive, hitting and strangling us. They wanted to instill fear in the kids so we’d be too scared to disobey them,” she added. 

She even planned to run away but a classmate told the staff about it and Hilton was put in solitary confinement, a punishment that would sometimes last 20 hours a day. The continued abuse transformed her bubbly nature as she was having “panic attacks” and was “crying every single day.” Her attempts to tell her parents about the torture were also foiled as teens at the school were only allowed to speak to their parents only once or twice every three months. 

“We were cut off from the outside world. And when I tried to tell them once, I got in so much trouble I was scared to say it again. They would grab the phone or rip up letters I wrote telling me, ‘No one is going to believe you.’ And the staff would tell the parents that the kids were lying. So my parents had no idea what was going on,” she explained. 

When she turned 18 and returned to New York, her confidence was shattered and her traumatic experience had become “something she was ashamed of” and “didn’t want to speak of it.”

But today, she finally feels like the “nightmare is over.” Currently, she has no plans of opting for legal recourse as she wants to focus on being the voice of protest against behavior improvement schools that employ physical and verbal abuse. 

“I want these places shut down,” said Hilton. “I want them to be held accountable. And I want to be a voice for children and now adults everywhere who have had similar experiences. I want it to stop for good and I will do whatever I can to make it happen.”
