am i to thin
I am 5 ft. 2 in. tall and weigh 143 and have people telling me that I am too thin as well even though according to my BMI I am still overweight. I want to get to 130, but 125 would be even better.
I also think it is just them not being used to seeing me thin. They obviously haven't seen me nude. You are fine. Just do what feels best for you.
