How do you get somebody help, when they don't even realise they have a problem?

Like when they should be the one looking after you, and could easily get pissy about my interfering, especially in the state they're in. I know, I'm normally the first one to say 'nobody can be helped unless they accept their problem' but how do you force the issue? Because seriously, I can't fucking live like this any more.
