The latest sees the Alo Yoga face revealing it's the opposite, telling Vogue:"I remember being really young, I'd say like eight, nine, 10, like around that time. And I remember having shortness of breath and going to my mom and telling her that. In hindsight, now I know that that was obviously anxiety."And She's JudgedContinuing, the Versace ambassador said: “There [are] going to be those people that say, ‘What does she have to worry about? What does she have to be anxious about?’ And I’ll never sit here and say I’m not fortunate…[but] I’m still a human being at the end of the day. And no matter what someone has or doesn’t have, it doesn’t mean they don’t have real-life feelings and emotions.”Kendall's Xmas post also comes as sister Kylie Jenner returns to Instagram after a long silence, this following the Travis Scott concert tragedy.
