After watching an episode of Nancy Grace in which a forensic doctor described how simple it was to prepare a particular suicide method I could not help but think how simple and nontraumatic that way of suicide would be.

I don't think that was quite the intent that Nancy had intended for her audience but it was informative. A bit
too informative.
I later described this method to my pdoc and told him if I ever chose to kill myself that way would be my choice and we talked about the method pros and cons. Pretty much we decided there is no such thing as a perfect method because nothing is foolproof and it would really suck to be brain damaged but live.
Of course I am not any where near wanting to kill myself then or now and hope I don't ever make that choice but my point is that thinking about suicide is not abnormal (IMO) until you get to the part where you intend to follow through and attempt suicide.
(I did attempt suicide by overdose when I had postpartum depression and was not in my right mind and my call for help to my ob doc was ignored as he said just drink a beer).
Stupid doctor 
What I learned from that experience is if you are really in crisis and you don't get the support you need keep seeking help from other people and if all else fails go to an emergency dept.
