There seems to be an expectation today that we should always be in good mood, and unhappiness is taken as a sign that something is wrong. Therefore we are continually bombarded in advertising with images of smiling and cheerful people and families.  When we find that the reality of our day-to-day encounters with life involves occasional challenges or simply ordinary routine, we can be tempted to think that something is wrong. The prevailing model has no place for the dips in mood or even depressions that are a normal part of life and which can be seen in the cycles of nature. We have to learn not to fear those moments when we do not feel completely in control or lose our sense of direction for a while. Often our psyches are wise and know when they need to rest.  As Jung states here, the lack of energy is marking a period of transition as the energies needed for growth are stored for the future and  this is felt as a lack of energy in the present. This can happen over a weekend or over months or even years. What I have learned in listening to people on their journey is to hold a space and trust, even though the meaning of what they are going through is not clear just yet.

There are moments in human life when a new page is turned. New interests and tendencies appear which have hitherto received no attention, or there is a sudden change of personality. During the incubation period of such a change we can often observe a loss of conscious energy: the new development has drawn off the energy it needs from consciousness. This lowering of energy can be seen most clearly before the onset of certain psychoses and also in the empty stillness which precedes creative work.

Jung, The Psychology of the Transference, CW 16.
