"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. "
