Id be interested to know how you did it.
consequently, the person i hold anger towards came into plat chat and i was able to carry on a civil conversation with no issues LOL
It's not as complicated as it seems. I am not saying there is anything wrong with feeling anger or sadness or whatever it is feel it then you let it out. What ever way works for you cry, lift heavy weights, break inadament objects... Then you put it behind you close the door and move on. It's not even a matter of telling the other person you forgive them it is setting it in your head that you have.
I didn't for some traumatizing repressed childhood issues the exact same way I did it for some less traumatic tumultuous relationship I had. It is only as complicated as you make it in your mind.
