I’m so sorry to hear your news. At this time, my husband has been diagnosed with terminal cancer, so I can understand some of what you’re feeling. Having said that, my mum died when I was 14, my sister was 6 years old. We weren’t told about mum, I guessed she had breast cancer when I was 12. Please, please take some advice on how to handle your DiLs illness from the children’s point of view. My dad was an alcoholic and left me to care for my mum and look after my sister, the house, shopping, cooking, washing my mum and feeding her. She even died in her bed with me in the early hours of the morning. Yet, I wasn’t allowed to go to her funeral because I was ‘too young’. So, for me and my sister, there was no final goodbye. No chance to grieve. For my sister, mum was there and then she was gone. That was 50 years ago now but both my sister and I have suffered in one way and another since she died. Things have moved on now and children are considered more. Please look into how this awful, untimely and tragic situation can affect her children and how best to handle it.
