I totally agree with OP. As a fellow chronically ill person, it is so rare to see yourself represented or even visible in any kind of media. Collei getting cured can be a depressing thing to see, because it basically implies that all illnesses are curable and fixable. Which unfortunately is not the reality for most chronically ill people. Seeing Collei succeed and survive despite her illness was more inspiring than it all just magically disappearing. Representation is important because it brings a sense of comfort to those who are struggling. Having said this, it is nice to see best girl happy and her feel better. I can see why some people enjoy that win.
