I like how he didn't belittle the act of trying to suicide.
The solution doesn't really match for me and the whole emotion change in this chapter is drastic but who knows? I can't make assumption that she really doesn't have remaining suicidal thoughts but a new expectation changing life is true, i think. At least for that moment
Maybe they can try to include her usual friends in that scene, just to know how her usual friends will react
Still, with minimal witness hopefully her reputation in school won't get worse. I think suicide-trying student will have bad reputation if known, even by rumor
