Joan Didion: Adoptive Parent

This review of  Blue Nights, Joan Didion's memoir of her daughter's death, excerpts some parts of the book about the adoption of Quintana Roo:
What would have been Quintana's seventh wedding anniversary prompts a stream of reminiscences. Didion recounts that she was in the shower when Dunne told her that a doctor had just called to say there was "a beautiful baby girl" up for adoption. She burst into tears.

Quintana, as an adopted child, worried about abandonment: what would have happened if Dunne and Didion had not been home when that all-important phone call came, she asks. What would have happened to her if they had had an accident on their way to picking her up from the hospital?

Didion, a worrywart even in happy times, obsessed about things happening to her daughter. "All adoptive parents fear that they do not deserve the child they were given, that the child will be taken from them. Quintana. Quintana is one of the areas about which I have difficulty being direct," Didion writes.
Is Didion right, do "all adoptive parents fear that they do not deserve the child they were given?" Is that your fear? 

I heard an interview with Didion this week where she talked about her guilt that her daughter died, that she felt she had an added responsibility because of the adoption, that she was given the child to care for, and she felt she failed in that responsibility.  Do you have that feeling of added responsibility?  I remember a friend whose daughter adopted from China had broken her nose shortly after she came home.  When the mom called me, she said in despair, "I've had her for less than 6 months, and I already broke her!"
