On the subject of forgiveness or emotionally severing ties. Has that actually worked for anyone on here and if so what was that like? Specifically I mean letting go of those negative emotions so the person who hurt you doesn't have power over you anymore.

It's something I heard about mostly from a Christian angle but I'm curious if people have tried it and if so was it helpful? As I can understand the reasoning but it kinda feels like to do so would be betraying ones self in a way. That it means accepting all the pain and damage caused by them. The rage and sorrow that never got a proper release.
