There really isn’t one particular mood that encompasses what depression feels like. Some people feel overwhelmingly sad, while others find themselves irritable and quick to anger. Others lay in bed, not wanting to get up because they feel that the world is too overwhelming to face. Those suffering from depression might experience symptoms that feel like a physical illness akin to the flu. Whatever a person may feel, if it lasts beyond a 2 week period then clinical depression might the root of the problem.
