Yeah, it is more or less in my family, my mom has the same body structure as me, and the same with my grandmom. Most of the time, the people that make those comments are bit overweight or either obese. I never really hear it from skinny/normal weight people...
It is never too late You can still love yourself for who you are and you are not less beautiful if you look different than before or if you look different than anyone else. I understand it takes some time and patience for you to be happy with yourself, because even I am still on that process
