Do you know how to calculate your BMI (body mass index)? Google the phrase and you can find calculators online, you only need to enter your weight and height. That can give you an indication about how healthy your weight is. As for the part about attractiveness and how you feel in your own skin, that's much more subjective and we're often our own worst critics. You definitely must have something really beautiful about yourself, look for that in you ... Just make sure you're not depriving yourself of a healthy diet with everything that you need.
