During a recent episode of Keeping Up With The Kardashians, via The Mirror, Kylie admitted to hating her life at times, and told family members she didn't want to talk about Bruce's decision to become a woman.

"Kylie's the one we're really worried about. ... She's having a hard time dealing with this," Bruce told the cameras. "I do everything I can to try to stay in touch but she doesn't want to talk about it. She's just shut me out lately. "My big concern is just that we've had such a close relationship for so many years and my kids are everything to me. ... I don't want her to go away, emotionally."
