It becomes impossible for us to move forward. We become angry and withdrawn. It's hard to even tell friends about our pain, because we don't want to hear "I told you so". Because every time we had taken the narcissist back, our friends and family didn't support our decision. They were right, and now being in pain after the narcissist final blow to us, hearing "I told you so" is just to painful.
And we just cannot take feeling anymore pain than we already in.
So it is relieving when we find support in other places. When we read stories similar to our own, by other victims of a narcissist/sociopath. It is these supportive places that some of us find strength to begin to heal.
Once we start the healing process, it becomes easier to began to share our story. We don't feel so much shame about what happened to us. It becomes very clear that we were not betrayed by a normal human being, but we were betrayed by a personality disordered individual, with no moral compass, and unable to feel empathy for others. Knowing this helps us to realize we are not sick, or doomed.
What happened was not our fault, we were just another convenient victim of a very sick and twisted individual.
Knowing this helps us to begin to move forward and live life again with gratitude and a new appreciation for life.
