I do not think that there is much you can do, as to end your pain, it passes it on to other people. They will be sad no matter what, but in my case the way I see it, I will not be alive at that point. I think the only thing that someone could do, is to write a note, which could act as closure and can mean that those left behind will not be left with unanswered questions. Whatever happens, I wish you the best.
