Books with a protagonist very similar to Georgia Lass from Dead Like Me

I’m looking for books with protagonists very similar to Georgia (George) Lass from Dead Like Me, especially as she is in the early episodes.
She’s introverted, introspective, apathetic, and cynical, a college dropout working a dead-end job, feeling aimless and disconnected from life. She spends most of her time in her own head, constantly narrating her thoughts through dry, detached internal monologues —I’d love something where that kind of inner voice is central to the narrative

She doesn’t care about being good or bad, in her view, you’re screwed either way.
She’s never been in a relationship (possibly even a virgin), avoids intimacy, and keeps her expectations low because she believes expectations only lead to disappointment. She avoids getting too involved in experiences to protect herself from caring too much, which also means she doesn’t really enjoy anything. She’s socially isolated, sarcastic, emotionally distant, but intelligent and observant.
I’m looking for character-driven books with that same detached, existentially bored energy. Female protagonists preferred, but not required.

I know this is very specific, but I really connected with this character and related to parts of her personality. I kind of hyperfocused on her lol. Thanks in advance!
