insecuritues T_T

ok, so im pretty sure i care a LOT less about my bodies appearance than most girls my age (i dont care about shaving, dont watch my weight, etc etc, ive always kept the mentality that as long as i dont smell like ass or feel like ass im doing perfect) but lately ive been really insecure about how my face and voice ;~; ive got a pretty high pitched voice and a LOT of speech impediments, along with a babyface and lots of acne... i know those are pretty normal for a kid my age to have (well.. aside from the speech impediments of course) but they still mess me up a bit... recently, i spoke to this girl who was only, like, TWELVE and had the face and voice of an adult (and she was also a total JACKASS but thats beside the point) and it suddenly made me REALLY insecure... i know that in the long run of life, what my face looked like when i was a freshman doesnt really matter, but cant a girl complain?
