Emotional about moving out, so I’m searching for “books you need to read in your twenties” or just with characters figuring out how to *adult*

I've got approved for a job (as a bookseller, yay) and am moving out for the first time in about two weeks.

While I'm super excited about becoming more independent, all these quick changes also scare the shit out of me tbh and I'm in an emotional spiral about moving away from my mum (we're really really close and have been through a lot together. She's my favorite person).
I know it's time. I know it's the right thing to do at 24 and it's literally a dream location & apartment, five minutes from work BUT still…

do you have any recommendations for "books you need to read in your twenties" or books with characters in similar situations, learning or struggling how to be an adult, moving to a new city? (+ points for queerness).

Thanks in advance!🙏🏼
