How can I gain a little weight?

Well my face looks perfect but when it comes to body, they said im sooo skiny! but I ain't getting sick. I eat a lot of healthy food, I exercise. I never eat little foods never! But why am I ain't getting bigger? heavier a little? a little fatter? But why? WHy ? why why why why why???

I wouldn't worry about it if I was you. Everyone has their own pace for development. See, I myself am very skinny, and as we get older the weight you want now will start catching up with you. So enjoy being thin. As long as it isin't some kind of disorder your best bet is leaving at that and continue your healthy living.

Im not worried but I always get that words. "?" This words: 'you are sooo skiny, nana!'
But thanks for the advice.

Eat!!!

Hmm..I eat a lot but... im still skiny. Well I guess you're right, I am picky too
