The book is about a girl, I think 18 years old. It has a lot to do with manic depressive disorder. Her mom also has manic, and is kind of crazy. I seem to remember one part of the book where her mother chases her through the woods or something? In the end, the mom kills herself, and the girl goes to college. As she gets on the train at the very end, she looks up to the sky and says something to her mother. I really want to know what this book is!
