I hear you. People off themselves for all sorts of reasons that might not look "good enough" to someone with chronic pain, etc.
But keep in mind,...we rarely (if ever) get the entire story. There could be much more going on. Issues that he/she can't even imagine communicating, even here. I'm like that about some things.
The job situation, break up, argument, etc. "may" just be the catalyst (straw that broke the camel's back) that pushes them off. It's possible that the real reasons are so horrifyingly disturbing that they're unmentionable.
Here I am in what must be one of THEE most accepting groups on the entire internet, yet I still can't bring myself to the intro. thread or openly share everything that's bothering me. It's too raw, too bare, too disturbing. Anxiety's a bitch (so is selective mutism) and it extends all over the place.
I do not think you're wrong, however.
Some people can indeed be healed and some situations can be fixed, accepted or adapted to.
