Forgive and it will set your heart free. Here are some steps that can get you there free. Feel your anger, feel your sadness as you want, feel whatever it is you need to get all those emotions out, write it down and then throw it away in the universe. Give yourself a certain timeframe in which you will no longer remain to go on with those emotions. Now comes the hard part, trying to convince your soul that the other person deserves to be forgiven. Every time this hurt comes into your heart, say to yourself "I forgive John for what they have done". Every time you start to go over the scenario, and start to get angry or sad, instead replace it with "I forgive John for what they have done". You might not believe what you are saying at first time. But sending that message out into the universe will eventually help break the karma chain of black energy that links you together with an invisible line of hate.
