Laura Kerr has written a lovely and profound piece. She quotes, too, from Carl Jung:
A collective problem, if not recognized as such, always appears as a personal problem, and in individual cases may give the impression that something is out of order in the realm of the personal psyche. The personal sphere is indeed disturbed, but such disturbances need not be primary; they may well be secondary, the consequence of an unsupportable change in the social atmosphere. The cause of disturbance is, therefore, not to be sought in the personal surroundings, but rather in the collective situation. Psychotherapy has hitherto taken this matter far too little into account.
