There are few more painful experiences than an agitated depression: the combination of pervading anxiety and deep depression. Which can result following such common trauma as divorce or unemployment. Or even apparently nothing since, as I never tire of saying, the unconscious is very powerful and one must respect its power.
Because feelings reflect both mind and body, they cannot be separated. Thus does remaining in bed make depression worse and incoherent flight increase panic. So when altering the body through constructive activity, as by involving oneself in a work or household chore, the agitated depression lifts and, sometime later, its unconscious cause (if one exists) may surface.
