Society puts an enormous amount of pressure on people to conform and aspire to having a body that looks a particular way. This pressure can result in compulsive behavior that can be far from healthy and create mental stress that is incredibly difficult to deal with on your own.
“To be nobody but yourself in a world which is doing its best to make you just like everybody else means to fight the greatest battle there is or ever will be.”
—E.E. Cummings
