Knowing there's always an escape plan available can be a source of comfort.

I've also seen it that way and have been coached by my psychologist on it. Ultimately, for me, it was best to set an expiration date. The date on which I could finally do it with minimal guilt. This actually had several positive impacts in my life.

First I quit using suicide as a first or second resort when coping. Instead it has become more of a fleeting thought as I know I'm "not allowed" to do so yet (while obviously still lingering as seen by my initial comment). Second was giving me a finish line. A finite date where I knew the pain would end (chronic conditions are the worst). Third was a reminder that I only have X days left, so make the most of them. It turns death from this amorphous thing into a clear cut "this is it". I KNOW when the ride ends down to the hour.

The caveat to this is the same as literally everything else in my life: I reserve the right to change my mind as new information is introduced. I've made a commitment to not do it until the date I've set, but as the date approaches, I'm not ruling out examining the evidence as presented and potentially pushing it out longer.

A LOT of peace of mind here.
