Depression will encompass an enormous range of emotional states, not all of which will be classified as illnesses. If you look at what happens at any given moment in a person’s life, there will undoubtedly be quite understandable reasons why someone is feeling low, or worse. These states have often be referred to as “reactive” or “environmental”, or in more academic language, “exogenous”, which means, coming from outside. In such a state will a patient have been propelled into depression caused by an event or a series of events in their lives which has triggered a lowering of his or her mood.
