Kat, thank you so much...fascinating stuff. I'm going to my local bookshop today & order a copy of the book you recommend. I'm really quite overwhelmed by the response to this thread. Good people from all over the world offering advice, words of comfort & encouragement...sincere & heartfelt. One day, don't know where or when, I want to meet all of you & say thank you properly. What a special day that would be.
                               With Love,
