To all those people to whom l have sent emails, which were polite and friendly, and have not replied....... l do not care! It is time to let go of you all and turn to face my future where l am. Tonight l heard my mother may have throat cancer. She is 82. Three years ago she had major heart surgery. She is a fighter. My sisters and l - with the help of my partner and theirs - will help her fight this one. My younger sister gets married at the end of this month. Around the same time my mother has to have a biopsy. She will not want to miss the wedding. Whatever happens we will ensure she does not. My mother lives each day to the full. I intend to learn from her. If l am now invisible to various people to whom l have been professionally attached in the past, then let it - and me - be their loss and not mine. I have a lovely home and a loving partner and family. I will turn to my research and get on with my life.
