Authentic feelings do not last long beyond the event that generates them. The primary exception is grief, the worst case being the death of a child. Normal grief has wide variations in time / intensity.

Racket feelings are used to coerce, blackmail, threaten, manipulate, and avoid. The skill of using racket feelings is learned in childhood when one or another feeling is prohibited, unauthorized, or punished in its expression. Children then learn to use another feeling - that is authorized - as a substitute as a method of "expressing" and "using" emotions. This then becomes the racket feeling.

Learning about one's feelings and being able to sort them out into authentic and racket categories is an extraordinarily valuable skill for a person to learn.
