So very true. This is just one of the great things about Al-Anon. Slowly, you are encouraged and the behavior is modeled for you...to take the focus off your qualifier (the person who "brought" you there) and turn it on yourself.
It's okay if you talk about the qualifier when you share, but you start to notice over and over again, that many of the people are able to shift that focus and start talking about themselves and what they are doing to heal, even if they mention the qualifier(s) from time to time.
When I first got into Al-Anon, SWOT, I was the epitome of that description you provided, about first my ex-husband, and then my son.
I didn't need the focus to be on ME!!! I was the okay one. (hahahahahahahahaha...she laughs wryly).
Gently, slowly and kindly, Al-Anon showed me another way to live. Thank goodness.
