If you want to end things, walk away from your life and career. Stand up from your desk, put one foot in front of the other, and proceed in this way until you tire.
This could mean switching careers, getting divorced, cutting ties with friends, moving far away, or a combination thereof. After all, suicide would end all of those things too, in a worse way. So if you were willing to do that most final and extreme action, why not just say screw it and start driving? After all you'd have nothing to lose compared to suicide.
In some cases just the realization that one can make changes is significant.
I'm kind of suicide those original career goals at the moment, but want to make sure I gave life somewhat of the biggest attempt I could.
I think the problem with it that if you are at that point, you're already feeling utterly hopeless.
Suggesting that someone who's suicidal:
* willingly loses everything in their life
* starts from nothing
* fights their way through the chaos that is building a new life for yourself
* in a strange and unknown place
* with no support at all
is naive and unhelpful.
To me it also feels pretty dismissive, up there with "you should smile more".
Your comment shows a lack of understanding of suicidal thinking across a population.
