I think KA having what she thought could escalate to a medical emergency abroad where who knows how close the nearest hospital is, if they'll make her pay out of pocket, if the care is any good, etc could be very frightening. She may have been having a legitimate panic attack or simply being dramatic it but I think it's fairly understandable.
One thing the articles make clear, though, is that it seemed that KA wanted yoga to save/fix her. I don't get the idea that she considered herself some sort of zen goddess at all 4 years ago, and I doubt the pandemic really helped anyone's self worth. It seems like she used yoga for therapy/self help when she needed real therapy (or more of it).
