Painful experiences in our lives can cause bitterness in oour hearts. Bitterness affect the way we view and relate to other people. In fact, bitterness can even cause a physically fit person to be sick.
According to psychologist Dr. Carsten Wrosch, “Persistent bitterness may result in global feelings of anger and hostility that, when strong enough, could affect a person’s physical health.” If bitterness can get you sick, it can also greatly affect the quality of your life.
Dr. Wrosch explains further, "Bitterness may forecast patterns of biological dysregulation (a physiological impairment that can affect metabolism, immune response or organ function) and physical disease."
This somehow explains why bitter people often experience stomach pains. They also suffer from indigestion.
Bitterness can be avoided through the process of self-regulation. A bitter person must be engaged and disengaged to other activities in order to overcome their negative emotions. If the bitterness is caused by a failure or frustration, the person must find ways to achieve his goals and continue with his previous plans.
