Books about young adulthood

I’m a recent college grad and rather nervous about that fact, I’m looking for novels about young adulthood and the things that come with it, something similar to the first few hundred pages of “a little life” I really like the parts about their young careers and romances and failures. Other books that have the vibe I’m looking for would be the middle section of 11/22/63 when the protagonist is teaching at the high school and the parts of Empire Falls that are about tick, although I loved all of those books the whole way through.
