Hi! I'm a 112 pound 12-year-old girl who is 5‘6". I have a very hard time believing that I'm skinny even though all my love ones say that I am. I really want to believe them and I try so hard, but whenever I look in the mirror I look and feel so fat. My brothers say it's my eyes or my brain that's telling me that I'm fat, and that I should believe them when they tell me that I am very skinny for my height especially. And I know it's just my brain trying to put me down or my eyes making me see someone that I am not, but for some weird reason I believe my brain or my eyes every single time. I see pretty girls online and they're very skinny and I tend to ask my brothers who's skinnier or who's fatter and they say that I'm the skinner one every time. I get so excited one moment and then I go to the bathroom the next moment and I'm crying myself to sleep. So I wanna ask you guys to tell me the truth, am I skinny or am I fat?
