Not rated mature but has mentions of attempted suicide and depression.

This isn't a book as much as it is a dairy. It is written from the perspective of a girl who is depressed, though I don't know if the girl is fictional or the author.

The writing style is very thoughtful, and I would reccomend it if you are looking to read something deep and heartfelt.

Overall, I would recommend you read it as long as the themes don't act as a trigger for you.
