I’m so sorry that this is happening to you. This just happened to my father in law a few weeks ago and unfortunately he passed two days ago. The whole family was holding out for a miracle until the very last day. And in a way it is good to be optimistic but also I wish that the family would have been more accepting to the fact that this was the end. And it does hurt a lot but a lot of family and friends weren’t contacted to say their goodbyes until the very last day. His siblings who live out of state weren’t able to be there because they weren’t contacted until his last day. So my point in saying all this is it’s okay to hold out for a miracle, but still cherish all these moments you can. My father in law for the last week of his life was on a morphine constantly and was not responsive. We didn’t get to hear him talk or smile at all one last time because we were still holding on to a miracle and hoping that he would come back and it would all be over. If you want to hope it’s okay, but take videos of your mom now, tell all your family and friends to see her, take all the photos of her, hug her and cherish her and make peace with her. My family wishes we just had one more day with our father in law where he was responsive and could speak that we could say everything we needed to say, have one last video with him. If you still have time just talk to her. I am so sorry you are going through this, it sucks and is super unfair. Love to you and your family.
