I just don't buy that hardship of being pretty stuff.
the only girls that won't be your friend because of your looks are the competitive ones. you could still befriend all other girls, and don't include the boys when girl time.
if you don't like the other stuff you can just get fat or downplay your looks. many girls do this to avoid unwanted attention.
you don't HAVE to be pretty, and most girls aren't without accentuating, diet, etc.
regarding your socialization from day one around your looks, again if you wanted to pursue other things like degree, career, etc, without it influencing then just downplay it.
