Increase fail?

Hello, I'm 18.161cm tall, female, and I'm trying to gain weight because I only weigh 46.7kg. The BMI calculator says I'm of normal weight, and my body burns 1300kcal when I'm at rest. I have an extremely fast metabolism, and my father has type 1 diabetes. I'm completely healthy, though, and don't have any illnesses….

Am I tall?

Hello everyone I'm a female, almost 15, and 164 cm tall. Is that tall or short? I often feel very tall and unfeminine. My boyfriend is almost the same height as me. About 169 cm. Am I too tall? Some people say I'm rather short. I'd like to be shorter myself, though.
