Looking for books about friendship with a character who has a mental health challenges

I know this sounds like a weird request, but I’m a sucker for books like this (specifically ya). It can be set anywhere but I’d like for at least one of the characters to have something that affects their mental health and possibly also their friendship with other characters (things like ocd, bpd, self harm, eating disorders, etc.)

I’ve already read:

Turtles All The Way Down

Those Pink Mountain Nights (don’t think that really counts for this tbh)

Wintergirls

Girl in Pieces

[edit]: Wow I did not expect to get this many recommendations in just a few hours. My tbr list is so high now but in a good way T~T
