It’s all a lot to take in, but may I suggest the following? Give up
guilt. It doesn’t help, is possibly misplaced and uses up
your energy. Your daughter means well, but the later cancer is discovered the fewer options you have about getting rid of it. Preparing for the end of life is a useful and life affirming thing, at any age. It doesn’t bring on anything other than perhaps a more relaxed approach to something that will affect us all, and mainly at an unknown time. You are not alone which is both unfortunate as many people are in your position, but also good as people who have been through this best understand how you feel but also about what to do, how to cope, how to express yourself. You will find the network a practical help. Try to take things one step at a time at first. Breathe. Best wishes.
