The recent season of Keeping Up With The Kardashians has only just come to an end, but the trailer for the 17th season has already been released, and Kortney Kardashian is in a teary mess over turning 40.

"It almost makes you analyze like, where you're at in your life. It's just giving me anxiety," Kourtney tells sister Khloe in the clip.

"I feel like I want to cry. [...] 'Cause then I'm like, I have so much, and I should just be so happy," Kourtney says.

Khloe then asks her older sister if she's happy.

"I mean, I am," Kourtney says before adding, "Sometimes I'm like, I'll just do stupid sh*t to distract from really thinking about stuff that is maybe more important. I don't know. But then half of me is like, live your life. Have fun." 

Khloe then tells her: "If you're happy, that's all that should matter for any of us. But I really don't think your soul is happy…I think you feel incomplete somewhere. But you're scared."
