Hey there littlekings and welcome. I grew up with an alcoholic mother and codependent father and later found that the skills that we so useful to survive in my childhood home were counterproductive to an adulthood of healthy relationships.
I second the recommendations to go to Al-Anon, but I would also suggest that 6 - 8 therapy sessions with different counselors would never have cut it with me. When I found counselor I went once a week for five years. We started out in crisis mode (my marriage was falling apart), and then moved into the real work. Therapy is a not a quick-fix. I have one friend who refers to it as a very slow, controlled nervous breakdown in the safest place imaginable.
Five years probably sounds like an eternity but it was well worth it to get to where I am today.
