I am an elderly person. I would, under various circumstances, seek to end my own life. But I would never advocate suicide because your life is your business, not mine. If I committed suicide I would do so as a rational decision and would do it in a way that would be relatively painless and certain, eliminating any possibility of failure.
In my case, I would go to a place that I know where there is a high cliff. I would sit in a certain spot and take drugs that would make me drowsy. When I became too drowsy to sit up I would topple and fall a very long way to a certain (drowning) death. My suicide note would be mailed that same day, a copy to all my children, with reasons explaining my decision, and what to do with my belongings.
My body would be in a large river that flows eventually to the ocean, so that I would be giving myself back to the mother of all life on our planet.
Or else I would make a stencil that spelled "fuck you" and tape it to the back of my head and blow my brains out with a 12 gauge. Spell "fuck you" with blood and brains all over my walls.
You know, be creative.
