Kourtney Kardashian has branded her family's reality tv show "toxic" and said it made her "cry all the time".
The 42-year-old said her time on Keeping Up With The Kardashians made her more "sensitive" as she battled it out with her sisters.
In a frank interview with Bustle, Kourtney said: "Shooting our show, it became a really toxic environment at the end for me.
"It made me really sensitive, I would just start crying all the time."
The Poosh founder spoke about how the siblings would bicker, and that she would often hit back with comebacks about her sisters' weight or appearance.
But she said that she reached a point where she "didn't have anything mean to say".
"I was used to always being a b**** and having no feelings."
The mum-of-three admitted to not being in a happy place during the filming and she ended up playing a character.
She also revealed how once the show came to an end in June, she said how she embarked on a "therapy journey".
Kourtney backed away from the show for seasons 18-20, fans were surprised to see she'll be a part of their new Hulu series The Kardashians.
She said how she was met by criticism from fans who said she looked like she was "already over the show" after the trailer was released.
But the reality star said as far as her work is concerned, she's the "happiest" she's ever been.
Kourtney, who shares three children with Scott Disick, will be joined by fiancé Travis Barker on the new show.
She also spoke openly about how she was "really indecisive" when it came to relationships and admitted that she would have to ask friends for advice before making a decision.
Kris Jenner also spoke with the publication and said that she and the rest of the family were a "little too hard" on Kourtney.
The 'momager' said that she "dragged" Kourtney "kicking and screaming", hinting that she almost forced her to be as enthusiastic about KUWTK as her sisters.
