I have gotten some help from Al-anon also. I did not grow up with active alcoholism, but I think both my parents did. I got to this site (and Al-anon) for another person in my life, but both have helped immensely about my family stuff that honestly i don't think I even recognized on my dad's side of the family.
The Adult Children Side of SR might help also. That is the side that in general has put me in closest touch with my family pieces.
