Mavis,
When I finally completed my 4th step last year, (it took me almost a year...) I also did a "Family of Origin" study on my own. It was quite interesting.
I copied this if you're interested:
Family of origin work typically looks at the family you were born into and your parents' background.
Family of origin work can help individuals to:
understand their origins and learn from the past, so that they will not perpetuate unhealthy patterns, either in themselves or in their own family;
understand the consequences of wrongs that were done to them;
break free from the past;
detect generational issues and deal with them;
detect and deal with the roots of bitterness/resentment;
deal with any unresolved guilt; and
improve extended family relationships.
Hugs,
