Children's Book Girl Fantasizing

Hi, so I read this book at McKinney Elementary School near Portland, Oregon, sometime between 2006-2008. The illustration style is very distinct as it features realistic pencil sketches, each page alternating between black and white and full color to represent reality versus fantasy. The story follows a young girl who feels disconnected and disappointed with her life and her family. It focuses on her dreams and how they contrast against all the dissatisfying situations in her life/family. One of the fantasies is about owning a black kitten named "Night", with a very luxurious illustration. In the end, she connects with her family and is able to be happy and grateful with her life despite not having all of her fantasies fulfilled. Thank you in advance for anyone taking the time to read and respond!

I don't know about pictures, but could it be Coraline?
