am i not good enough?

soo
in my high school majority of girls are skinny and there is me who is you can medium/healthy?
people often say I am fat or pass comments first it didn't affect me but now it does, I started skipping meals, and daily workouts, and at this point, I even started sh and now idk how to cover it. I am scared that if I will get gain more weight and people will bully me idk but life suddenly seems complicated I feel like I am not good enough for my friends or my parents
