Quite a question. I have suffered for 30 years and I think that the only thing I have noticed that is distinctly different between the two is that demoralization can be helped with positive socialization and that relief can be long lasting. The depression is only mildly and temporarily helped through socialization and requires concentrated therapy and medication. This is based solely on my personal experiences. I am not a medical professional. I have always been intensively curious so am always seeking new knowledge.
