@tnt69, denial is a part of this journey you, your sister, your family didn't choose to take. I think you might appreciate this article about how hope and denial can work together and how hope can be reframed.

Hospice care includes a team of people from doctors to nurses to social workers to chaplains that work with anyone in the family that can use comfort and care. I want you to know that you can call your local hospice and ask about services available for you, to help you accept and to learn what you can expect.
