What is the name of this young adult book?

I can't remember the name of it. All I can remember is that the main character's name is Cole and he's kind of psycho or something. I remember in one scene he gets attacked by a bear and it's raining; his bones are broken and he's lying in the middle of the field eating fish guts he puked out (funny how that's the only scene I remember!)

What's the name of this book, if anyone out there knows?
