I'm obsessed with my body.

I dont understand why but I am obsessed with my body like that is all I can think about now a days. I know that I am not fat but I want to be thin and perfect and beautiful and I'm none of the above. I actually do know some part of why I can't stop thinking about this is because the media tells us that you're not beautiful if you're not thin, which sucks because I am a 155 pounds with a bust of 41", waist of 29/30", and a hip of 39/40". This isn't large at all its about average, but i still want to get a smaller waist I want a waist that is like 25" or smaller, like what the hell. I could never get that like ever and no one that I've ever heard of has had a 41' bust and a 25' waist, that just doesn't happen ever. I try and eat healthfully but I can never seem to stay on a that plan for too long. I end up eating all of this crap like ice cream or some shit. I hate this because as a teenager all I want is for boys to notice me thats it, and they barely notice me and when I try to wear something comfy no one gives me a second look and I hate it so much. I want to be notice and I want to be liked and I want to be thin like the other girls. Why can't I be like the other girls?
