Mark Twain said is credited with saying "I have known a great many troubles, but most of them never happened."
Talking about death - helping a loved one get their head around death - is a part of life. Do NOT worry about it. Just plan and prepare so you can get on with living!
We have countless jokes online and in person about nonstop phone calls at all hours begging you to extend your car warranty - even when you don't own a car! But we don't talk about death. AND we all have death in common!
Upon death, even if your legal paperwork is completed will there be problems? Tell others about your wishes. Make changes as often as you want but be sure your loved ones know. Problems arise when loved ones disagree. Money can do that to wills.
You don't have to discuss death daily. Yet you need to face that we all will die. Give yourself a rest sometimes but remember that each day is precious.
