Constant bitterness can make a person ill, according to Concordia University researchers who have examined the relationship between failure, bitterness and quality of life.
“Persistent bitterness may result in global feelings of anger and hostility that, when strong enough, could affect a person’s physical health,” says Carsten Wrosch, a professor in the Concordia University Department of Psychology and a member of the Centre for Research in Human Development.
Unlike regret, which is about self-blame and a case of “woulda, coulda, shoulda,” acrimony points the finger elsewhere — laying the blame for failure on external causes. “When harboured for a long time,” says Wrosch, “bitterness may forecast patterns of biological dysregulation (a physiological impairment that can affect metabolism, immune response or organ function) and physical disease.”
