I went through this in April of this year. Mother and I had been estranged for 17 years, she was dying of cancer and asked to see me, after a hell of a lot of thought I decided to write to her as I felt she only wanted to see me to ease her own conscience. The letter s returned to me unopened and so I decided not to go and see her, she then died. I did not attend the funeral either, my choice. Do I regret either not seeing her or not attending her funeral, I don't. That's me, it's your depiction in the end and you have to do whatever you feel is right. My thoughts are with you, good luck and take care xxx
