We then take that knowledge into future friendships and relationships and we do better. I know I have. What I needed to do was to heal myself. I have done that. I continue to grow and to learn.
Past relationships are in the past.
I cannot heal what has happened in the past. I can only unburden myself of it as others unburdened themselves of me and my chaos when I was borderline. I needed but never had. It was like banging on my head on a wall. It felt so good when I stopped it.
