Suggest me a book: I’ve been feeling a disconnect from myself and life in general….

Hi, I’ve been feeling quite the disconnect from my life lately (in my 20s) just life/ myself in general. I don’t know why I feel so out of body lately or just feeling like I’m floating through life if that makes any sense. Even though I’m in therapy, I always turn to books as an outlet. Does anyone have reccs that could possibly give me some insight, advice or just comfort? Thank youu
