~ I'M OVERWEIGHT ~

I'm 13 and i weigh 159lbs. but lost two lbs so I weigh 157lbs. I was never overweight before. It was until I weighed myself and took a BMI test. I was kinda sad because I never felt like this before. i don't know how to feel right now it is even harder to do things like i get winded just going up some stairs at school.
