What to read when you’re so fucking depressed?

Hello, I’ve never been in a worse spot mentally. My life is pretty much sucking so royally bad as of late. It doesn’t help that I had to read Crime and Punishment for English class (senior in high school) and saw elements of myself in Raskolnikov (not the murder bit). I’m feeling so awful about life, and I need a book that will teach me to love what I have. I’d prefer it not to be a self-help book, maybe a story that subliminally teaches you to be appreciative to gain a new outlook on life with its themes. Help me, please. Btw yes, I’m in therapy, but it only does so much; I'm not sure how much hurt I have left in me.
