One of my greatest fears is reconnecting. I just may go back with her.
It's a rough spot to be in. x
For me it was literally breaking the addiction to the obsessive thinking, which was like the challenge of "whatever you do, don't think about an elephant." Which of course brings to mind the very thing we're trying to avoid thinking about.
So much mental/emotional energy was devoted to X -- I remember the anxiety at first of trying to find other thoughts to fill that space in my head. It was a sound of one hand clapping kind of dilemma. The more I let go of the anxiety, the more I realized that I was giving room for new life, restored life to naturally fill that void. Or that the void in itself was safe and OK -- I didn't have to be clenching my fists to prepare for the next crisis.
I think your fear is protecting you, and the fear will gradually morph into a more peaceful wisdom which maintains your healthy distance. I believe that's really the voice inside you that is talking, the fear is just the emotional zone we stay in for a while.
Be gentle with yourself -- and post as much as you want to. We're here to listen and support.
