Kendall's absence from NYFW, while shocking, isn't expected to be permanent. Her choice not to walk in this leg of Fashion Month is not her way of retiring from the runway, but is most likely indicative of a deeper struggle. 

On Season 14 of Keeping Up With the Kardashians, we saw as Kendall called Kris Jenner during an anxiety attack over NYFW in 2017.

In the heart-wrenching scene, Kendall tells Kris that she's having an "emergency" and Kris later spoke in her confessional interview about how Kendall has a tough time dealing with all the pressure of stardom. 

"Kendall struggles from anxiety and I think she has so much going on that she gets herself worked up," Kris said. "Kendall gets the most anxious during Fashion Week, trying to juggle it all is overwhelming."

While it seems like Kendall is taking a leave of absence from her runway work this go-round in NYC, it doesn't look like it'll be long before the model returns to walking.
