Alz has been getting much worse later and quality of life isn't there along with poor physical condition. This is tough on everyone (but I don't think I can blame him for his decision) so we are struggling- is there pain in taking this path? We just got hospice involved and they are providing some help in the last few days.
When I look back, the person I was helping in this situation kept telling me how tired she was. I now understand that her body had started the initial phase of shutting down. Don't talk about things in the room, hearing is said to be the last sense to go. Tell your Dad how much you love him and that it is all right to let go. Bless you and your family at this difficult time.
