Here is a link to a post about some lists I posted regarding Adult Children of Alcoholics and our unique characteristics. I thought this might be useful to you. I think it is great you and your mom and sister are discussing these things. When I first start investigating this stuff and learning about alcoholism and addiction, I asked but none of my many siblings was interested. Most of them are paying for it now, unfortunately.
