Book: Turtles All the Way Down by John Green

The main character is a high school student with an obsessive compulsive disorder. It centers around struggles between her and her mind.  

"You know there is a problem. But you can't figure a way through to fixing it.”

Please pay more attention to kids's struggles along the way, not only their glory in the end.
