Another wonderful article, Sylvia! What you describe as looking fine on the outside and dying inside, is what Thoreau called ‘living lives of quiet desperation.’ Most people, as you know, do just that.
We are not meant to live desperate lives. Our bodies (physical and other) are designed for happiness, for living a deliberate, not a desperate, life.
You write of these things so clearly and so well. Anyone new to these concepts would be fortunate to have you as a mentor.
