Does getting even produce a real sense of satisfaction?

Whenever I get hurt, there is this tendency that I curse or say bad things about a person or people who have hurt me. It is a normal initial reaction you will get from the person who have been hurt. A plan of taking revenge is also part of pacifying what I am feeling but then when I get back to my rationality, I will think optimistically that things will be better by tomorrow and that revenge won't yield a positive effect but will only lead to more heartache. I will just let time heal the wounds and would reverse what I have said and thought earlier. Instead of cursing, I would pray for myself that I am hurt and that I am hoping that a better understanding on what happen will eventually took over me. I also pray for that person who have hurt me, asking god to help this person not to hurt more people. It may sounds impossible but I already did it. In 2004, My new boss who didn't like me tried to say things that really hurt my ego. I was handling the position for the past 4 years and has master all facets of the job. Then one day, she called me and tell me that she was holding my promotion because she thinks that I am not yet capable of my job that I have no time management, etc. I really really feel bad then. The following day, I tender my resignation. I was out of the company after two weeks. I really hate her for taking away the job that I love. At first I did curse her and said so many bad things about her in my mind but as the days goes by I offer a prayer for her and that I told myself that I already forgave her. After a year, I heard that she resign from the company to join another company then on the second year, I heard that she was already jobless because she has management issue re: on how she treats her staff. I honestly feel sorry for her but I think that is how the law of life works. When we are too confident, a knock will come in our lives to make us humble.
