If someone wants to commit suicide, likely because of intense pain and a degenerative condition, the best thing for them to do is the “Mexican solution”. Which is not suicide, per se, but literally to take a holiday in Mexico, rural Mexico.
You can rent a pleasant place to stay, and hire locals to help and take care of you, and to bury you there when you die, with a local doctor to certify your death, and to keep prescribing you the drugs you need.
And you can eat good food, and drink good drink, smoke if you like, and be generous to the local people.
Before you go, you can put your affairs in order, and bid farewell to your family, with them knowing that they will never see you again.
So how, and how fast do you die? Without the interference of doctors and hospitals, and taking care of your own pain, in such a place you will perish in your own time, but far faster than you would in a hospital up north, full of tubes and using a ventilator to breathe, barely alive until your family is impoverished.
You will not die by your own hand, so it is not true suicide, but instead a willingness to let death come when it may.
And there will be considerable joy in denying the American busy bodies the ability to play with your dying body, and mutilate it with an autopsy, and require an elaborate an expensive funeral. And it will foul up their paperwork royally, though your death certificate will be legal and final.
It truly is “the Mexican solution.”
My dad did it a lot simpler, he told all of us that he wanted out @ 92 because he couldn’t totally care for himself and just refused to eat or drink until he died.
No one in the family tried to intervine as it was his choice.
If (when)that time comes for me I think I will take an easier way out.
