How you feel about your own suicide is a pretty profound question.
I feel a certain resigned inevitability to the fact that some day I will CTB.
When I was about 15 I tried to kill myself by hanging. It failed obviously.  But it left a feeling that it was always going to be part of my life.  CTB was inevitable in the same way that retirement is.  But it was not real, just a vague notion.
But things changed recently.  
I woke up with the sense of urgency that I needed to start planning for it.  Not that it was going to happen today, tomorrow of even next year.  But I needed to be ready for it by planning the means, the locations,  choices like public, private or even broadcast, about who finds me and will there be a note or just a mystery.
I have this curious feeling that I will just wake up one day and say - it's now!  I grab my ready and waiting CTB bag with the gear I have tested and need, arrive at the designated location and CTB.
This is one of the reasons I have joined this site to talk about feelings like this and, if I can, provide support to members of the community.
