Name of a film

Hi I’ve been hurting my brain last 2 days trying to think of a film I’ve seen and can’t remember the name of it. There is a young girl with short black hair no one really likes her in school then she meets another girl and they become friends. They end up meeting men for money and become best friends.

Is it Ghost World (2001)?

No it’s not that oh god it’s doing my head in :weary:
