I understand where you are coming from, for sure; it was one thing to heal from PTSD, and it is another task to developmentally catch up with emotional maturity and socialization skills.
Some books that helped me understand what I needed and how it naturally develops, so that I could create ways to create it in my life: The Magical Child, by Joseph Chilton Pierce, was wonderful. I also found Piaget's books and publications very helpful, since he was a very humane, developmental psychologist. And lastly, I like another of Pierce's books, The Drama Of The Gifted Child (most of us), informative about challenges that I came up against.
And learning all the social nuances that were beyond my grasp since I was frozen in fear, I don't have a book for that; still gaining the knowledge as I go, and am more alive to noticing social graces.
