Some people object to expressing emotions by using cuss words and obscenities. You should use whatever words are naturally expressive for you. Many therapists also doubt the efficacy of catharsis and abreactions. Private expressions of feelings, as in this self-help method where the intent is clearly to reduce the unwanted emotions, could result in decreasing both internal emotional stress and overt expression. You may want to try it and see how you respond but use caution.
Much more research is needed.
Remember, anger, fears, and sadness probably grow, if one obsesses about the situation. In fact, just talking about a highly emotional problem and expressing your feelings with a friend is not always helpful. If the focus is on how to stop the unwanted feeling, the talking may help. So, anything that distracts our attention or helps us forget the distressing situation should be helpful. See if venting your feelings helps you put the troubles aside or if it just reminds you more of the problem.
