Female rage/ depression/ hope?

I’m looking for a book for a friend who just got broken up with and now she’s really struggling with the heartbreak goes back and forth between anger/ angry at men and depression/ feeling unlovable/seeing no future. I know being there for her and supporting her is pretty much all I can do but I thought I’d get her a book for Christmas. So I guess it could be either something along those lines of validating her anger (think wife poisons husband) or self-help type uplifting? Though I think she’s less into practical solutions and more into poetic exploration of feelings. Or maybe something super riveting emotionally or story wise to distract her and get obsessed with instead? Any ideas? I’m not decided on a genre but I think she’s not really into fantasy and sci-fi.
