Existential therapy (of the American, existential-humanistic tradition) starts with the belief that although humans are essentially alone in the world, they long to be connected to others. People want to have meaning in one another's lives, but ultimately they must come to realize that they cannot depend on others for validation, and with that realization, they finally acknowledge and understand that they are fundamentally alone. The result of this revelation is anxiety in the knowledge that our validation must come from within and not from others.
