Barb, here's part of the response from my friend. I'm posting it here in case others on TE might benefit from it. There's also more private info and I will PM that to you. This friend is a long time social worker, one of the most loving and wonderful people I know, and had an adoption that they had to end, years ago. She is as recovered as anyone can be, but it can still raise tears sometimes.
She said to search on this website for other parents who have been through this: www.pnpic.org
(The Parent Network for the Post Institutionalized Child). She also said that she had placed an anonymous notification in the Adoptive Family Magazine in attempt to connect with other families experiencing a disruption. She got some responses and moved forward with talking to those folks.
"My predominant feeling is one of gratitude. I have loved and been loved;I have been given much and I have given something in return...Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and an adventure." O. Sacks
