Ah gotcha. Ctb by gunshot is gory and violent as fuck. Like you say 'eating' the gun, you need balls of steel for that shit. Or be drunk, drugged, impulsive, plain desperate, honestly I dunno but I know I could never do it. I'd be highly likely to mess it up, misfire the gun and survive as the Elephant Man. Truth to tell OP there is no easy way. SN is the least worst option if you can't get N (which most can't or don't). Doesn't mean it's in any way a pleasant prospect. Lately, to be honest, I find myself thinking about how to survive old age in the event that I have to. Knowing myself, knowing how survival instinct works and how it's almost invariably 'easier' to go on existing however shitty it may be, I honestly can't say for sure if I'll go by ctb or 'natural causes'.
It's a shit show. I empathise with your situation and hope you find what you're looking for.
