My mum is slowly dieing from cancer, And she has asked me to not let her mother know and one of my sisters know. There is a lot of family history. I feel like I'm stuck in the middle . I have had to keep this secret in for so long and finally had to tell one of my aunts today that will tell my nan. Was I wrong to do this ? I understand it was my mums wish, But puts me in such a difficult postion . It's tearing me apart as it is :(
