When I entered retirement years at age 62, it had followed the passing of a dear elderly friend whom I had cared for the ten years previous. I was at a major change in all facets of my life.
Such periods of long term care, often leave the care-giver with a sense of emptiness. The pivot of their life has been around the dear one's care, and now that pivot is no longer there. It is not uncommon to experience a form of crisis in their life, and great uncertainty about what lies ahead. It certainly must require a healing of the loss, reassessment, and assimilation of many aspects, before any sense of new direction emerges.
