My MIL died today at 2:43 pm EDT. Today was her 85th birthday and she lived a great life. Her decline was sudden and rapid as only a week ago she was driving her car and shopping. I was at her bedside and watched her take her last breath, and it was a peaceful passing. We made sure she had pain relief and oxygen support.
Sure, we could have instituted CPR, IVs, cardiac meds, ventilation. We chose not to and let her die with dignity and grace. How selfish would we have been to inflict the horrors of active life support, which are indeed rough. There comes a time to just let go.
