I understand what you are saying. I came from a large family and my older sister and one brother and I spent a lifetime looking after the others. I am the last survivor and about five years ago I decided that I had done enough for the family and turned the responsibities over to the oldest surviving niece. I am a widow (married for sixty years to a caring, wonderfull man) and in my old age I decided to live my life concentrating what was the best for me. The result that I have been abandoned by my children, nieces and nephews but I have developed a very fulfilling life without them. The Internet has opened new opportunites to explore the world outside of my immediate surroundings. I hope you can look at this time in your life as a time of absolute freedom to explore and find new meaning in your life.
