"Analysis of the detailed accounts of more than 3,000 recent crying
experiences found that the benefits of crying depend entirely on the
what, where and when of a particular crying episode.
...
"Research has shown that the effects of crying also depend on who is
shedding the tears. For example, individuals with anxiety or mood
disorders are least likely to experience the positive effects of
crying. In addition, the researchers report that people who lack
insight into their emotional lives (a condition known as alexithymia)
actually feel worse after crying. The authors suggest that for these
individuals, their lack of emotional insight may prevent the kind of
cognitive change required for a sad experience to be transformed into
something positive. "
