Am I depressed or just cynical?

You're 16 and not being logical. A lot of teenagers go through this, probably because of hormones. Believe me, in a few years you will see the world and your life much differently. And a few years after that, it will change yet again. You will look back and think, 'what was wrong with me'? So, try and be optimistic knowing that in a few years you will not feel this way.
