Can you perhaps tell us a little more about yourself, how old are you? would you say that you are a codependent? I don't know, just a little more about you so that we can get to know you better.
Also did you check out the forum right below this one for friends and family adult children of alcoholics? Even though you said that you parents are not alcoholics, I think you might be able to relate to that section.
The friend I was talking about started in AA, still goes, but he also added in 2 ACOA/ACA meetings each week.
