Arghhhh please help me real quick?!?

i haaaate my height. i've had three people today at school ask me if i was in sixth grade (and i'm in freaking eighth!) a lot of people call me "little girl" or "midget" or "that short girl" how should i respond the next time someone makes a remark about my height?! none of the other short girls get teased! they get called "cute" either that or they just don't get called a name at all. thanks!!! just some comebacks would be good or some snappy remarks!1 something along those lines :P thanks so much!!!! i will love you forever if you answer
