As someone who has pulled himself back from suicidality, I absolutely abhor the expression "died by suicide".

If I had gone through with it, I would have killed myself - and any euphemisms being thrown around would serve no-one at all (especially not those still living in that hole).

I would much rather have it framed as me having done something unforgivably stupid and completely preventable - but as a society we'd much rather reject that reality and instead refuse to acknowledge that more often than not the signs were all there; that not only was the death an irreversible act of idiocy, but it was also something that we could've and should've stopped yet did nothing to prevent.
