Reply #63: no, I think the situation you've described is different than the ones...

...I meant to address in a more general sense. In that situation, I would naturally do all I could to help the person contemplating suicide, regardless of who it is, but I'd be especially eager to help someone close to me, as you suggest. But I would stop short of legally or physically preventing them-- ultimately, that decision has to be theirs to make, and I can do all I can to try and influence their decision, but I cannot presume to make it for them.

Maybe sometimes you just have to say goodbye, I think.
