Thank you all for the kind, thoughtful comments. I limit my attempts of trying to contact her because she accused me of "stalking" her!!! Just because I would ask other family members about her and at first I did try emailing and calling often. So I stopped that when I got that response from her. I wish her a Happy Birthday every year. And every year that goes by without any attempt by her to contact me just makes me feel that much more hopeless about the situation.
