Turns out something like a National Advance Directive Month already exists. Only it’s a day not a month, and it’s called National Healthcare Decision Day. You can find out more about it here. The site is worthy of a look as it has a more comprehensive list of advance directive forms and websites than the one I compiled. (Including a Psychiatric Advance Directive designed specifically for people dealing with a mental illness. I know, I know. Who wants more choices!? But there it is.)
BTW, Loretta has been working with the dying for about twenty-five years and does a great job describing some of the gifts that are also available-but-usually-overlooked at the end of life. If you’ve got the time and interest, her website is worth a look, too.
