This post blew my mind. https://dearadoption.com/2018/11/06/dear-adoption/
“As an adoptee, my trust issues ran the gamut from not trusting at all, to trusting too much and too easily. I don’t know which came first, the chicken or the egg, but I would go through times where I trusted no one at all and then shift to suddenly trusting someone with my whole life story. Not surprisingly, this would tend to scare people away, too much information too soon, giving me a reason, at least to my way of thinking, for swinging back to the other pole, where I trusted no one.
“That all said, the root issue for me is fear, the fear of the unknown, the fear of rejection, and the fear of being deeply, deeply, hurt.
“The process of healing from adoption related trauma, for me, has been like peeling the skin off an onion: there seems to always be yet another layer, and tears are often involved.”
