Ok so yeah I am using my older sister's account real quick but I am 10 years old and I weigh 75.5 pounds. I am under weight. I read the signs and when I eat I eat less for some reason. I don't have anything wrong with me, like I haven't been through anything dramatic or anything that would scar me. I do not think I am fat or anything because I KNOW how skinny I am. My arms are REALLY skinny and I have REALLY thin legs! I have a stomach but my ribs are showing and I am getting worried. I saw a video on Youtube about it and I do not want that to happen to me! For example, I eat breakfast, right? I eat a lot then but when it comes to lunch like 5 hours later I say something like, "I just ate." or "My tummy doesn't feel good!" I worried to death! Please help me! My mom is worried too!
