Small girl rant

I'm 5'5" and usually between 115 and 120 pounds and I am tired of being told to go eat a sandwich or I need more meat on my bones. People don't seem to realize that it doesn't matter how much I eat because my metabolism doesn't let me gain weight very easily. I'm small and petite because of my small skeletal frame and a very good metabolism. I struggle to maintain a  relatively consistent body weight. I always feel self-conscious when I go out to eat with friends espeshaly new friends who don't know me very well yet because I don't eat much. I have a small appetite but that's just how I've always been ever since I was a kid. I eat small portions but I eat 6-8 times a day unless I'm on my attention meds that decrease my appetite but not my much. They just make me not eat as much for lunch but I eat like 2 dinners and usually have a late night snack. I try to eat healthy food but not because I am worried about my weight but because I'm sensative to foods and if I eat a lot of junk foods my body starts to feel sluggish and it's hard for me to get anything done but most people don't know that they just assume that I'm worried about my weight and apperiance. I've had many friends comment on my weight and appetite not knowing that it's one of my insecurities because of how many times people who don't know me have suggested that I might be anorexic or bulimic. I'm not anorexic or bulimic and I hate it when people suggest I am because those are very serious conditions that aren't to be taken lightly. I love my body and I love my size. I know I'm lucky to be able to have my figure naturally and I am grateful that I'm not anorexic or bulimic. It seems like in our society to day small petite girls are automatically assumed to have some kind of eating disorder so that they can stay so small. I think it's a shame that in our society it doesn't seem to matter what size and shape you are there always seems to be a reason for it to be wrong. I'm very happy and confident with my body but there are many girls who aren't, I even have a younger family member who has her own body issues because of what people have told her.  I hate that there are other girls out there who have been told by strangers that it's wrong for them to be skiny or it's wrong for them to have curves or larger bodies.  I hate seeing what it does to their minds and self esteem. I always try to tell my friends and family members how beautiful they are just the way they are but unfortunately because of what society has told them time and time again they don't believe me or anyone else who says they are beautiful.
