Everyone feels a little down sometimes, but sometimes those feelings don’t go away. When feelings of sadness, hopelessness or numbness persist for more than two weeks, it may become clinical depression.
Depression is one of the most common mental health conditions in the United States, with nearly 7% of the population suffering from it in any given year. One in six people will experience depression in their life. Depression and substance abuse often go hand in hand, with many people turning to drugs or alcohol in an attempt to relieve depressive symptoms.
What Are Symptoms and Causes of Endogenous Depression?
Depression is primarily characterized by feelings of sadness or lack of interest in things you once enjoyed. Those experiencing it often feel hopeless and apathetic. While many people picture someone crying and obviously sad all the time, many experiencing depression seem outwardly normal. Internally, however, they may feel numb and disinterested.
Exogenous vs Endogenous Depression
Depression can have many causes. Many people develop it after a traumatic event or major life change, such as a divorce or the death of a loved one. In the past, this was called exogenous depression, meaning it was caused by an outside event. It’s important to note that exogenous depression is not the same as grief, however. Everyone feels sad and stressed after a major loss, but normal grief or stress involves periods of relief and happiness that increase over time. Depression is persistent and doesn’t show signs of improvement.
There are also some people who experience depression that occurs for no apparent reason. This is defined as endogenous depression, meaning depression that comes from within. Endogenous depression is just as real as exogenous depression, although some people struggle to accept it because they feel they have to have a reason to be depressed.
