I feel what you're goin through man. I'm not a psychologist or anything, but I dont think the confusion and depression came because of being a teen. I had the same prob when I started smokin couple years back. There'z really nothing that can help you feel better except for yourself. You gotta sit and rethink your shit until you overcome that feeling of hopelessness. Understand that it's not something you wanna be going through, and that it can be better with juz chillin and realizing that althought life is hard, life is too short to not be at your best. Even when the hardest situations come and slap the fuck outta U.
