That your mother has hospice care at all, tells me she cared more about herself, than she ever cared about you. Regardless of how long it takes, whatever is wrong with your mother is terminal. She will not survive it.

You do not know me, but I ask you to trust me anyway. Hospice workers have seen it all, the very best and worst of humanity. I promise you, your mother has not fooled them or deceived them about herself, or her daughters. They see your mother clearly. They see you too. Taking care of your mother, is their gift to you. Accept it.

Let your mother die believing she was who she wanted to be. The truth survived her lies and it will survive her life. The truth belongs to you.
