This is intended to be a serious airing of people's personal reflections on the prospect of suicide, as in the thoughts you've had regarding possibly taking your own life one day. The pros and cons, strictly as pertaining to yourself and your life situation. This is not intended to be a thread for the philosophical discussion of suicide. And please, no religion, as one's religious beliefs, if any, are one's own affair.
I'll start off by saying that as I contemplate my future, I can see a number of scenarios in which one day suicide might present a reasonable and practical solution to a problem. These range from profound sorrow and loneliness, to having no close family left, to illness, to age, and just possibly to the state of the world in combination with one or more of the above. I am 52 now and in no hurry to leave this life, but one day, since we all have to go sometime, controlling the time and manner of my death may indeed seem desirable.
As implied, this type of suicide to me is not a tragedy. Rather, it affords control, dignity and hopefully a painless option. I suppose, in the end, if one has really chosen to end things, the method really doesn't matter, and a bullet to the head would presumably be painless--provided one has decent aim. I would, however, prefer what has come to be known as the "peaceful pill," among euthanasia advocates, something that sends you into an opium high, following which you fall asleep, at home, surrounded by your loved ones, and that's that.
