One of the world's highest-paid models, Kendall Jenner, recently admitted on Sunday's episode of "Keeping Up with the Kardashians" that she has been suffering as a hypochondriac ever since her childhood as a result of her anxiety.

Riddled with anxiety attacks and an obsessive belief that an undiagnosed sickness is affecting her, Kendall made an emergency call to mom Kris Jenner as shown during the episode. She told her mother that she had asked a doctor to give her a blood test because she feared that she was anemic.

According to the Kardashian-Jenner matriarch, Kendall has the most anxiety whenever Fashion Week comes around. In the episode, a flashback was even shown wherein Kendall had a breakdown inside an airplane and expressed the desire to get off the flight.

Jenner relates that much of her anxiety stems from the recent traumatic experiences that her family has gone through. She cited Kim Kardashian-West's robbery-at-gunpoint experience, her own experience getting robbed, as well as dealing with stalkers as contributing factors.

To add, Jenner said, "That's why I don't really like going out anymore. That's why I don't' tweet, that's why I don't Instagram. That gives me anxiety, too. I swear, it's the craziest thing."

Kris was quick to reassure Kendall that she has her full support and was willing to drop everything while in the midst of a meeting with Kim in order to rush to her supermodel daughter's aid. While she may have been worried, Kris said, "I've realized Kendall is one of the most independent women I've ever met in my life. And she can get to the root of the issue and the problem herself."

Kim expressed concern though, over their mother's situation by saying, "that's why she has psoriasis. Every kid has an emergency, every day." Despite the stress that situations like Kendall's anxiety attacks cause Kris, the mom-manager seems determined to find long-term solutions in order for Kendall to have less instances and attacks such as what viewers witnessed.

In the meantime, Kendall undergoes sound therapy, meditation, and acupuncture to help her deal with her anxiety. As for being a hypochondriac, Kendall says that now, she has to "try and be a big girl."
