You say externally things are good, so what do you think is the cause of feeling this way? How long have you felt this way? What type of treatment are you undergoing? By the way I have suffered with different types of depression off and on all my life, so I can empathize. But for me the extenal is not good at all, when it is I do feel better--but not necessarily all the time or perfectly so, in other words I can feel bad inside even when the outside day seems to be going well. But I have an understanding usually why that is so.
