Purely from an experimental standpoint, Chinny is fascinating. Borderlines (really all the Cluster Beezers) often don't do well in therapeutic settings because they believe their own lies and split the world into good and bad people. Therapists and other MH workers are generally "bad" because they call BPDers out on their shit and try to teach them to be accountable and grounded in reality. It's rare for a Cluster Beezer to get better - but those that I know who HAVE gotten better generally get to be really good at listening to difficult feedback and accepting criticism.
Chinny on the other hand has a dedicated group of sycophants who orbit her and seem to indulge and maybe even believe the delusions and lies she spits out. It's literally the opposite of what someone with her obvious pathology needs to succeed in life. She's like a much less affluent and differently mentally ill Kanye. Or Britney. She's surrounded with people who are latched on to her for whatever (increasingly meager) YouTube Bux she can bring in and not much else.
Hell, rail against her family for not stepping in, but it's even more evidence that her family doesn't give two shits about her. If they did, they wouldn't enable her bullshit, but they do.
It definitely does feel like she's due for a big fall anytime, and she gives away her own fear by asking her VIBs for validation or writing raging CPs out of nowhere. On some level she knows it, but it's probably not in the same way you or I would. She is the poster child for denial. But Cluster Beezers live in a cyclone of their own making - they complain about how everything is a roller coaster with zero insight into how they perpetuate it. So if I were a betting woman, I'd say yeah there's a big fall with something akin to rock bottom coming soon.
Those tens of thousands of calories she puts away daily are an attempt to plug the sinkhole in her soul that just keeps getting deeper and wider. She's never going to feel full - Spiritually, emotionally, or physically.
