Try Not to Breathe by Jennifer R. Hubbard

Summary:(from goodreads) Learning to live is more than just choosing not to die, as sixteen-year-old Ryan discovers in the year following his suicide attempt. Despite his mother’s anxious hovering and the rumors at school, he’s trying to forget the darkness from which he has escaped. But it doesn’t help that he’s still hiding guilty secrets, or that he longs for a girl who may not return his feelings. Then he befriends Nicki, who is using psychics to seek contact with her dead father. This unlikely friendship thaws Ryan to the point where he can face the worst in himself. He and Nicki confide in one another the things they never thought they’d tell anyone—but their confessions are trickier than they seem, and the fallout tests the bounds of friendship and forgiveness. 
Review: After enjoying Hubbard's previous book The Secret Year I was excited to give this one a try. I was a little bit surprised by how subtle the issues that Ryan was dealing with really were. He wasn't a character who had a big neon sign labeling him as crazy, even if he felt that way sometimes. This book was a more of an honest look at a guy who made some bad choices and did stupid things but in the end is able to overcome it. At some points in the story, I almost forgot what his issues at all.  I think Ryan is a character that a lot of people can relate to because I think everyone has those moments where they feel overwhelmed by life. I think the slow plot development is part of what made this book stand out for me and I really liked it.
