This is a very touchy subject for many people I can imagine, I can only go on what I think of the idea.
I have thought about such things before, I do not say I would commit to any of them, I am too afraid of Death itself to permit myself to do anything of the kind. I also find that many stories seem to be of people (stories I hear of anyway) who wish to escape the pain of life and spare their loved ones the grief of watching them suffer. I know this is not always the case but I still do not believe that suicide solves the issues. I just hope that I never see anyone I know commit to such an act.
The loss of a life, no matter how distressed, is a ripple felt across a world of souls. Never under estimate how many lives you may affect by your actions.
