She was a lifelong Catholic. So you can see what a troubling issue this is.

No, I don’t see it as a troubling issue at all especially since she was a Catholic. Or a Christian.
Death is a part of life. It’s difficult for me to understand young people dying, tragedies, etc. But they happen all the time.
The Catholic Church does not teach nor has it ever taught that when one is at the end of a long life, or any time of life, that artificial measures to prolong life are a part of doctrine. The Church teaches that euthanasia is wrong, assisted suicide is wrong. It has never taught that when one is dying that all medical interventions should be utilized. Circumstances play a huge role imo. Each situation, case is different. Euthanasia isn’t what the media pretends it to be.
Like I said, there’s www.terrisfight.org and www.priests4life.com (Fr. Pavone). Father Pavone can be contacted. If I had doubts, I’d contact him. Lotsa freepers have met him and hold him in high regard, even non-Catholics.
