I watched my Dad die slowly over 6 months from pancreatic cancer. He knew he was going to die - he was 83 after all and he said he'd had a good life & accepted his fate. We still had 6 months with him though with his banter & wit - he kept his sense of humour on the face of it alive (but what was going on in his mind knowing he was shortly to die I can't bear to think about) until he finally had to go to Ashgate Hospice.
I cherished the months we had left for obvious reasons.
Only once whilst visiting him at the hospice heavily sedated he muttered "Please God take me" whilst not being fully cohesive.
Yes. he died peacefully at Ashgate Hospice in wonderful care - they are absolutely brilliant there.
It's kind of assisted death with dignity.
Father-in-law was similar - had a heart attack & lasted a short while after that but eventually had to go in to a home where he passed away.
The boys & girls who look after these people are absolutely amazing
