My mom is in congestive heart failure and she told me today she did not feel she would live much longer. Do you think someone knows when they are dying? She is swollen ( gained 6 pounds in 2 days) her breathing is labored and she said her chest hurts all the time. The NH is aware and we have talked abut comfort measures.She has a DNR.
So, be with your mom as much as possible. Hug her. Hold her hand. Read to her. Just be there with her. Fill yourself with love and share that love in every way you can. Blessings to you.
After a fall to his head, my husband told everyone in the hospital that he was dying. We asked the doctor. She said there was no medical evidence to support that claim, but often patients sensed that better than the measures medical science has. We pulled all the grandchildren out of school and made sure everyone got to visit. He recovered from the head injury, ten years later developed dementia, and lived with that nearly 10 years.
So ... while I agree that your mother probably does know, I wouldn't want everyone whose loved one thinks they are dying without any medical evidence to suggest it to assume the loved one is right.
2tsnana, my heart goes out to you.
