My mom has literally become a cripple over night. She's uncharacteristically depressed. My Dad has the beginnings of Alzheimer's. I fear for the future of the elderly - vets and no vets.
My mom went thought a huge depressive bout three weeks when we thought she was going to die. She didn’t want to die, but finally made peace with it and got mad when she woke up the next morning because she was still in pain. Now that she’s worked through all that emotionally, she wants to live. I hope that your mom has the chance to do the same. I think that the realization that you’re at the end of your life and physically, it’s probably never going to get better, is devastating. I wish your parents well!
