Resentment is one of the strongest hooks that anchors a person to the past. The thing is, it is even stronger if it is ignored. It has to be directly faced and resolved. Resentment is a state of being in pain as a result of perceiving that you have been treated wrongly, unfairly and unjustly. It usually involves not feeling willing or able to accept someone or something that you reject. I call it a state of being because it is not an emotion in and of itself; instead it is like a soup of different emotions all associated with being treated unfairly. Emotions like dumfounded, fear, anger, disgust and sadness.
