Her wording is really bad, and I completely understand why "those girls" are upset. It's a Let Them Eat Cake kind of move. Goes to show she really isn't the smartest cookie, who knew.
However, I really do take issue with how people (here and elsewhere) talk about her anxiety. I know Kendall is an easy target, especially with quotes like that, but as somebody who has suffered from anxiety, I feel hurt and belittled by comments like "I just sucked it up." It's great if you can, really. I congratulate everybody who is able to lead a more or less normal life despite of anxiety. I've been doing that myself for the longest time, and I tend to throw myself into new (anxiety-related) challenges instead of running away from them, but I also know how fucking exhausting this can be, and I have the fullest sympathy and empathy for everybody who just isn't able, or willing, to endure three panic attacks a day.
More generally speaking, I find it a bit disrespectful to judge the severity of (mental) illnesses from the outside. We simply don't know, but we do know that she's under the public eye A LOT more than most of us can even begin to immagine, and it's not very surprising this has worsened her anxiety over the years. Sure, she doesn't have to be a public persona, but frankly, she's been quite private recently, almost disappeared for Kardashian standards. And we all know that's not something a Kardashian does unless it's really serious.
Maybe leave the anxiety part out of your rants, is all.
