Is it normal thin skinny passing out
I'm 18 - a senior in high school. I'm 5'3 and 100lbs. I look like I'm 12. I have chicken legs and stick like arms with a young face. I just feel like I'm too tiny. Lately, I've passed out 3 times in the past 3 months. But.. I eat a lot. Maybe not enough meat - but I promise, I eat more than the average teenage girl. So why am I so tiny and pass out? Should I be worried?
