No one can tell you this (they can but it's their projection then eh?)
Obsession with the neurotics of one's physical appearance is a ever growing poison, leading to self-destructive thoughts and actions.
Whatever you can do to raise awareness or be a positive change to this sickness (how little or local it may seem) and may serve as a transforming experience for people then I'd rejoice in one's efforts. But ppl often don't want to hear about various symptoms of suffering so easy to say "stop worrying"
On the other hand those who "worry" or are "activists" can't force others to care or "be worried" about it ofcourse, some people oppose to others planting trees and cleaning the oceans.
