While her mumma Kris Jenner and sis Kim Kardashian are in a business meeting, we see Kris drop everything for Kendall when she receives her phone call.
"It's an emergency," Kendall pleas.
Kris immediately leaves the room to call Kendall back, where she asks if she has eaten. "Do you want me to come take you to the hospital?" Kris asks.
It's then that Kris asks where she is and says she will be there in 15 minutes.
After Kris hangs up the phone, Kim asks what's going on.
"She doesn't feel well," Kris explains. "She's not quite sure what it is."
Then, to the camera, Kris explains further.
"Kendall struggles from anxiety and I think she has so much going on that she gets herself really worked up."
In the clip we also see a few flashbacks of similar times that Kendall has called her mum during an anxiety attack. One, when she is crying on a plane wanting to get off, and another when she is just explaining how badly it affects her.
Hopefully Kendall gets better asap.
