I'm 4'8 and 25. I hate it. I mean I love it at the same time because finding a man is easier for me and most men love our size better than tall and big (no offence tall woman).
I understand completely. My wife is petite and has a terrible time finding clothes that fit. This is because though she is petite, she is "built like a grown up".
On the upside, when you're older people will think you are younger than you are.
