I find myself obsessed with my appearance and i don't know why. i know i am a good looking girl, i've had boyfriends and lots of boys like me etc. i just feel like i have a hidden fear that i am ugly and i look for things wrong with myself to validate it. i want to stop obsessing and learn to just love myself but i don't know how. anyone else feel like this?

part of our culture doesn't let girls just be girls, everything is about how perfect you can be.
i suggest you do some google searches on the subject. i would suppose there's lots out there about this sort of thing.
do you remember recently seeing commercials on tv out dove (the beauty bar soap) running a program for exactly your issue. check it out.
i think we are all alike in the fact that we are most critical about ourselves. something for all of us to work on.
i doubt there are many boys who would bother waxing, shaving, bleaching, plucking, slathering makeup on, etc., but girls feel they have to. best wishes
I feel it is normal that you obsess about your appearance, but don't give you too much pressure, sometimes you don't need to be too sensitive.
