Do I Look Unhealthy? *see pics*?

You are VERY underweight. I calculated your BMI (Body Mass Index), and yours is 15,7, a healthy BMI is 18.5-24.9. You shouldn't feel self-concious about your height, but you do need to gain some weight for health reasons, it is very dangerous to have such a low BMI. If you find it hard to put on weight because of a fast metabolism etc, then you should go talk to your doctor about gaining weight in a controlled and healthy way.
