Death, the end of life, is not a bad topic. It is even something that should be discussed. My children always knew what would happen to them if, for example, I were to have an accident. My friends knew and know what I want for my end. Society, by the way, is not part of it... I used to imagine that it would happen at some point – I would die alone in a remote area and no one would notice for months or years. Since I have been in a relationship, this view has changed somewhat, but sad faces and sympathy are still not part of my plan. I don't find the possibility of being alone at the end threatening, but rather reassuring.
Same, I have discussed with my Son and Husband that if I die then what would I want to happen. But yes, I do not want to die in loneliness, this is what always bothers me. At one point of time it worried me like hell, I am ok now, but still I would love to have my loved ones around
