Pain is pain. Being a teenager is rough. Made more so by hormones, and amplified by being around other teenagers on a daily basis who for the most part also are having a rough time. I don't think teenagers should be scorned for complaining about it once in a while. I don't think teenagers should be scorned for not being able to handle it like an adult. If they could, then they'd be adults. They aren't adults.

Not to say being a teenager gives you a right to unlimited pity. There's a point where it becomes ridiculous. But I think that point is a long ways from where a lot of people seem to start to scorn teenagers for "angst".
