Western Society - What's Going On?

We previously learned about bulimia, anorexia, and binge eating, disorders where people's eating habits become harmful and abnormal. We also learned that these disorders may stem from a need for control, and are also almost primarily found in Western cultures. Recently, we also learned about another Western phenomenon: Dissociative Identity disorder. Formerly known as Multiple-Personality disorder, this is when a person exhibits two or more distinct and alternating personalities. Skeptics believe that this may be a cultural thing, of which eating disorders are a part of as well. DID goes along with the theory about hypnosis that it stems from a person's desire to basically put on a good show, and when urged by therapists, to create another side to themselves.
What is up with our society that we do things like this? Why in the world does this happen? Perhaps, it has something to do with a loss of control, as suggested by those knowledgeable about eating disorders. Westerners have it all; the technology, the wealth, the free time, etc. We think we control ourselves, and in a way, we do. We are, after all, more focused on the good of the individual, as opposed to communal welfare. This may be the very root of the problem. We are so plugged into everything else around us, and so focused on climbing up the ladder of life, that we lose part of ourselves in the process. The world, our culture, and our society essentially control what we do in our lives, what choices we make, and who we become. This may give a person, when and if they consider this idea, the feeling of a loss of control. Another way to look at this is to visualize the size of an ant compared to the size of a mountain. We would be the ant. In a culture such as ours, the disparity between the amount of control we have in our lives, and the actual amount of control we have in our lives is immense. Perhaps this is why Western cultures have disorders such as these; perhaps this lack of control is too much to bear, and these disorders are a way of expressing this feeling.

What do you think of this idea?
