I often think things like "If I had a gun, I'd be gone" or "if I had a bottle of N I'd drink it right now".
Truth is I don't know. I think I know, but then I can't actually know for sure because these methods are not available to me.
There are a few other potentials that are available to me, but they're risky, and I don't want to fail. I do think about them fairly constantly.
Partial, I practice, in the hope that I'll get there. That the more I get used to attempting, the easier SI will be to overcome. I know there are risks with this but I don't care if I "accidentally" die on one of my "practice" attempts, but sometimes thinking of it as practice helps push away the SI. I think I'm trying to desensitise myself to it. It also stops me from bemoaning the sense of failure if I just shrug and think, it was a practice run.
