Do you believe in depression and anxiety disorders?

Most people do get sad and anxious at times. But when it reaches a level where a person's functioning is impacted (e.g. They can't leave their house) it's beyond a matter of will power. The mental health field is still evolving and mapping the human genome is providing better insight into the clinical nature of various mental health diagnoses. A more enlightened view of mental health is holistic and multidimensional- rather than looking at the label and symptoms, look at the environment, physical health, spiritual health, etc to help someone rather than take an attitude of "pull yourself up by the bootstraps and get over it".
