Books for feeling okay being alone in life

I’m looking for a book to help me feel better. I often read philosophical or sad fiction and it helps in some ways, but I just want something that makes me feel less hopeless. Can be fiction or memoir. I love a variety of genres, but can’t really get into too much fantasy or sci-fi. I love lyrical prose and pretty words.

Some favorites, to know my taste (not necessarily on this theme) are all Shirley Jackson, Migrations by Charlotte McConaghy, Upstream by Mary Oliver, The Book of Form and Emptiness by Ruth Ozeki, On Earth We’re Briefly Gorgeous by Ocean Vuong, All This Could Be Different by Sarah Thankam Mathew’s, Never Let Me Go by Kazuo Ishiguro, What My Bones Know by Stephanie Foo, Circe by Madeline Miller, Really Good Actually by Monica Heisey.

Long list, just wanted to give an idea of what I like. I’m looking for a book that doesn’t focus on romance being the end all be all. Just something to make me feel a lot of feelings, but also that I’ll be okay. I struggle to make friends and I enjoy spending time alone, but sometimes it’s hard.
