some people don't like their looks, others have an issue with their weight....but those are all meaningless things that can cause serious issues in the long run or even be just a symptom of something more serious underneath the surface.
but at the end of the day you gotta realize that you are fine the way you look.
don't try to belong to a group, just be yourself.
and if you are different, then maybe it's the rest of the world that is strange and you are the way humans are meant to be.
