Have you ever convinced someone to get help?

I'm in my 40s and was diagnosed with "severe" clinical depression in my 20s. I've got it under control right now - I actually came here to ask about helping other people.

I just met someone on line who is the same age I was when I was diagnosed, and she's MISERABLE, close to suicidal, but firmly believes that no treatment can help her, because there's nothing wrong with her: It's just that the world is a sh*thole and most people just aren't smart enough to see it. She believes she's too smart for therapy, medication doesn't work, and everyone hates her.

Basically, she's me 20 years ago, except that I WANTED help. (Well, and also I was a psych major so I knew the biochemistry of it and knew medication does work, only I didn't realize I was depressed; I thought I had an anger management problem, but that's another story.)

Anyway, I know you can't help anyone who doesn't want help. I mean, I KNOW that, intellectually, but I still keep trying. Did anyone ever say something to you that convinced you to get help, or did you ever convince someone else?
