My lovely MIL died in 2016. She was 98 and a week earlier had been fine, living alone, a bit doddery but active and no medication. She had an internal bleed and an ambulance was called, she refused hospital and treatment. The Dr was lovely, she talked to her and made it crystal clear (nicely) that if she stayed home this would be the end. MIL died, at home, 2 days later.
What facilitated this was the fact that she had very clear wishes about her death. We discussed it in detail in the previous 5yrs. She put in writing exactly what treatment she did or didn't want and filled in the advanced directive at the Drs surgery.
They couldn't have been kinder. She was sedated and given a morphine driver. Carers came 4 times a day. She died as peacefully as could be managed.
If you want to manage your death you need to plan it much earlier than you think. And you can't just tell someone, it has to be in writing with your doctor.
I am so grateful for the way her death was managed, but it was, in part, due to her forward planning.
No-one should be left suffering.
