Your perfect for your age and height. But it all depends on bone structure. A petite bone structure, means your probably going to weigh less, medium or large leads to more weight. But yes, your quite perfect for your age. It would be a tad unhealthy to lose any more weight, you are a small girl already. If you feel less confident, I used to too. This is because, the way the female body is, when you look down, it looks like you have a gut, its normal! and also, when you sit and theres a flap of skin, everyone has it. So I guarantee your fine.. but if you feel weak, working out is healthy for the body... think about being healthy then rather loosing weight. Hope this helps! :) ~Syd
Are you really worried about being healthy? Sounds like a code...kids your age don't care about being healthy. You are perfect weight and should enjoy it, not worry about looking like photoshopped women on internet.
