> the serious ones don't broadcast their intentions (simply because they don't want to be stopped from doing it).

While this might be generally true (and it's especially true in the sense you wrote the message, i.e., there's a good chance that no one could see it coming), I would add something. It's, as I said, mostly true, but far from being the case 100% of the time. Ok, that was probably obvious, but the thing is: sometimes we interpret it as the contraposition (which is, after all, equivalent to the original statement): the ones who broadcast their intentions are not serious about it. And that's a huge mistake to make, when it happens to not be true. Someone who broadcasts that kind of intentions might be overdoing that kind of millenial "everything sucks" gallows humor you see a lot in Twitter... or they might be serious.

So, pay attention to people talking about that suicidal ideation. Many times, it's more than a joke.

BTW I also agree that in many cases an intervention can only delay the decision but not prevent it completely. I know it can be a hard pill to swallow for many people (and for good reason), but I strongly believe this to be true.
