In the newest episode of KUWTK, Kris receives an emergency phone call from Kendall, who tells her that she's not feeling well.
To the camera, Kris explains, "Kendall struggles from anxiety and I think she has so much going on that she gets herself really worked up."
Kendall herself has been very open about her anxiety in the past. Last month, she told Harper's Bazaar, "I literally wake up in the middle of the night with full-on panic attacks."
She continued, "I have such debilitating anxiety...everything is so horrible, it’s hard to name one thing."
"I just think that the world needs so much love. I wish I had the power to send Cupid around the planet, as cheesy as that sounds."
"You go online and you see everyone saying the worst things to each other, and it’s hard to stay positive. It’s hard not to get eaten alive by all the negativity."
Fortunately, the model says that she's "finally learning how to cope." Feel better, Kendall!
