She may have garnered widespread fame from her reality show “The Simple Life” with Nicole Richie, but the glamorous life that Paris Hilton seemed to lead was actually anything but, according to a new documentary.

In the documentary “This Is Paris,” debuting on the heiress’ Youtube Channel Sept. 14, Hilton, 39, details that her penchant for sneaking out to clubs and getting into trouble in the 90s led her parents, Rick and Kathy Hilton, to send her to several boarding schools in the late 1990s. However, it was her 11-month stay at the Provo Canyon School in Utah that left a mark on Hilton, who now claims she faced excessive amounts of abusive behavior while there.

“I knew it was going to be worse than anywhere else,” she says in the film, according to Page Six. “It was supposed to be a school, but [classes] were not the focus at all. From the moment I woke up until I went to bed, it was all day screaming in my face, yelling at me, continuous torture.”

Hilton goes on to reveal that she and her classmates not only suffered emotional abuse from the bullying, but physical as well, and one form of punishment if staff members learned someone was trying to escape included solitary confinement for as long as 20 hours a day. Things got so bad for the heiress and future reality star/entrepreneur that it started to affect her health as well.

I was having panic attacks and crying every single day,” she said. “I was just so miserable. I felt like a prisoner and I hated life.”

A trailer for the documentary (see above) shows Hilton revealing to her parents now, as an adult, what happened, admitting that she wasn’t able to do so when she was younger because of the punishments she would receive.

“I couldn’t tell you guys, because every time I tried, I would get punished by them,” she says as her mother is seen emotionally covering her face and rubbing her forehead. “I still have nightmares about it.”
