I remember thinking as a 12 year old about how sluttly girls my age were when they wore bikinis. It doesn't bother me now, but it does bother me how society pressures everyone to be perfect. This perfection that so many girls strive for is looked for in anorexia, bulimia, and it is still not achieved. From the earliest of ages these terrible role models like Britney Spears polluted the minds of the innocent. Girls would dance around half naked, and aspire to be just like her. Well, we can see how fantastic a role model Britney was. Sure, if you want to get sent to jail and shave your hair off. Even now, I sometimes look at my reflection and ask myself what's wrong with me. Here's the answer: there's nothing wrong with me, there's only something wrong with my perception of what I could be. Why is this relevant? Because society puts this idea of unattainable perfection into your mind, and you spend your entire lives looking for it for nothing. Even these glamorous stars are not perfect. Your brain is stuffed with a bunch of lies, and yet you still strive for this dream of yours that refuses to leave you in desolation.

This brings two things to my mind: Existentialism & the Great Gatsby.
Existentialism would dictate that one can't blame society for one's own troubles/problems. Everything ultimately is up to you. If society pressures you to do something, then ignore it. If you choose to adhere to societies precepts, then that's your choice and no one else's. As the adage goes, 'Man is condemned to freewill.' Therefore, everything he does is by his own choice. Thus, he is responsible for everything he does. Sometimes I wish I could fly across America dropping pounds of Sartre's works.
As for unattainable dreams, this definitely reminds me of the Great Gatsby. We ignore our free will by allowing our [unattainable] dreams determine our actions for us. Because we surrender our freedom and ignore our responsibility for our actions, we disintegrate into an abyss of meaninglessness, or at least unhappiness (kinda what you were saying).
I dunno, those were my (existential) thoughts that came to me when I read your blog.
I think society puts too much pressure on girls. I think a lot of has to do with the clothing styles in fashion and MTV.
