The word resentment means to re-feel...to feel again. Someone wrongs or wounds you; in resenting it, you re-feel the injury. And you re-hurt yourself. The Hebrew Talmud says that a person who bears a grudge is "Like one who, having cut one hand while handling a knife, avenges himself by stabbing the other hand."
