Although you are depressed, you are not the dark. It may envelop you, but it is not you. Perhaps we can call it an illness. Someday proper treatment will be found and the real you will emerge and stay. An Indian sage once told me that the natural human condition is one of happiness. When we leave that condition it is because we are encumbered by difficulties, and when we rid ourselves of our burdens our true personalities can re-surface.
