If this topic ever comes up in a group conversation, some people will chalk me up to paranoid and others will consider me well prepared. Perhaps it a bit of both, but I don't know that it's ever too early to start planning.
Beginning your transition from agressive treatment to palliative care or hospice is a good time to review your will and funeral arrangements or to begin the process of planning if you haven't done so already. There are many things to consider when planning a funeral or memorial service and planning ahead can provide you with peace of mind.
The worst time to start planning a funeral is after a death has already occured. Planning your own well in advance of your death can ensure that your family and friends can focus on their memories of you, rather than on the details of funeral planning.
