I mostly read this because I really liked The Sun Is Also a Star, but I was wary even before starting since I'd been warned about the way it deals with mental health — which is to say, it's inaccurate to the point of being potentially offensive. (Not having any personal experience or special knowledge, I'm certainly not qualified to make a judgment on this aspect.)

I think what makes me angry, as a reader and as someone with (mental/slight physical) health issues is more the fact that there are no signs that something is wrong, that the diagnosis is invalid. As an uneducated/everyday reader, there was no way for you to see it coming so it feels like it serves more for shock value than anything else. It also contributes to the discrediting of conditions like these, like "Are you sure you're really sick? How do you know?" And that bothers me.

Beyond that, I am not at all a fan of "girl meets boy. boy changes girl's world" especially when it involves the girl trying to "fix" herself for the boy. The way she carelessly endangers herself just to touch him, the reckless running away, even just the drawing away from/lying to her mom — none of that behavior should be romanticized like it has been here.
