WF, about "angst" => this is something a lot of teenagers go through during adolescence, it's "normal", now explained in biological psychology due to hormones running wild and affecting brains and emotions. Part of the painful path in finding your own personality, your way to adulthood. I often wondered why adults seem to shun literature dealing with this period. Maybe because it is too painful to remember what happened inside them as well? Or maybe because they are ashamed to be reminded of this?
Ah, I went through that period early and quite quickly. For me, it wasn't so much painful as silly. The degree of importance many teens will place on themselves and their petty, illusory concerns is quite astounding. Thus, I have no patience for any literature dealing with them and therefore stay far, far away from them.
