You have my sympathies. I am currently going through something similar; my mum is dying of cancer. Back in January, we went through all the documents - power of attorneys, will, funeral arrangements, etc. Been working on long term care/palliative care for when she can no longer look after herself. Also discussed how much treatment she wants. Yesterday we discussed the fact that she needs to make a list of people we should call. It is difficult to discuss someone's death with them. And the terrible thing is that we don't know when - next week, next month, next year...
