How?

I would go with: “gradually and carefully, if at all…”

Maybe break it into chunks, and start with relating your day to day experience, but lead into how and why it’s frustrating or stressful, etc.

I would advise against the ultra-blunt approach, where you just spontaneously blurt out “hey guys, i think i should kill myself today! Isn’t that awesome!!?” Or, who knows, they might be so torn between laughing and crying that they would actually listen.

I tend to think it’d be better to ease them into it, especially if they know you’ve “been there” before, and might carry a sort of constant subconscious fear of having to deal with… everything surrounding that, again.

I think the most important part here, though, aside from timing and “tact,” is that you must convey to them the reality of the treatments not really addressing the actual cause of the problems, and that you must sufficiently articulate what problems actually need addressing, before any effective treatment can be discerned.

(i said i’d comment here, check your dashboard, the address should be visible)
