Being Short 😔

Everyday I'm constantly being called short. I can't even go a day without being called short at school. And the bad thing is I can't tell if it's a joke or not because it's my friends (and other kids) who are calling me short. My sister says I should have the confidence and I shouldn't care but having confidence won't make me taller. And it's not even that I'm short I'm actually taller than most kids but apparently I look small. And I agree too every time I look in the mirror my head seems to big for my body... I don't know what makes me look small but it's bring down my self-esteem. I know us girls are supposed to love our bodies but how do I get taller? I know I can't be perfect but how can I make all the comments stop? My friends don't even know it's hurting me and I can't just tell them to stop or else there'll be rumors like "She's so mean" or like "She can't take a joke." And my mother is shorter than me so what if that means I'll stay at this height forever? Maybe I should just be thankful for who I am but it's hard.
