I think someone who is ACTUALLY going to CTB would overcome whatever it is and DO IT.
I agree. But I also understand that fear and anxiety prevent a lot of people (and probably most SS users) from following through.
Living isn't particularly easy, for most people, either. I think like all difficult tasks, it helps to take small steps, train yourself to be disciplined, and in the case of CTB, free yourself as much as you can of meaningless attachments.
I once had a grand plan, which involved a bucket list, a complicated but reliable method, a will, and a couple dozen personally-addressed goodbye letters. Plotting out the setting, pointless aesthetic preferences....Schemes and attachments, that I realized were keeping me from following through. I thought that somehow my death would matter, or that I could make it matter.
In reality, life is quite disposable, and death comes and goes at a moment's notice. I've let go of those worldly attachments and it's made my acceptance of death much easier. Once i'm dead, none of those things will matter, anyways.
It still won't be easy, but when you live like you've already died, it's probably a shorter hop to realize it fully.
