I am not getting any taller. I am 5 ft?? Are any of you this height?

I am only 5ft and a half an inch. I feel so short! almost every girl i know is taller than me! I had a doctors appointment today and she said if i grow anymore i will only grow a little bit. my mom is about 5'1 but my dad is probably a foot taller than her and so is my brother. i have a twin sister and she isn't going to grow much either. both of my grandfathers seem tall and my grandmothers are kind of short. one is taller then the other. I guess i wont having to worry about being taller than a guy when i am older. lol. are any of you this height? all grownups i know are taller than me, like my neighbor, she is pretty tall. all women i know are tall. is our generation getting shorter? i know i am only 13, but still. i looked at the charts. hahaha. So anyway, are you guys this tall?
