wow i am juz jealous on you!!!!
i hope n hope n hope becum thinner n thinner...if i hav underweight like u,totally my life could more perfect...
mayb u eat,sleep,then eat n sleep again...eat before sleep totally becum fat easily..
but if ur family all thin like u,it very HARD n COMPLICATED for u to gain weight...cause u own ur family genes n bones...
like my friend she eat everytime at school,but she til thin like a bone cause her family all skinny~~~
anyway hope ur wish will realise soon~~
