Numerous facts bear out the argument/statement/claim
that in order to recover speedily from negative emotion,
you should allow yourself to cry. You needn’t / don’t
have to be ashamed of crying. Anxiety and sorrow can
flow out of the body along with tears.
Consider the case of Donna. Her son unfortunately died
in a car accident. The intensity of the blow made her
unable to cry. She said, "It was not until two weeks
later that I began to cry. And then I felt as if a big
stone had been lifted from my shoulders. It was
the tears that brought me back to earth and helped
me survive the crisis."
