I too learned that alcohol was a coping tool for life's ills and much of what I learned about life came from living in an alcoholic family.
Unpredictability breeds uncertainty and fear.I remember being afraid a lot in my home because I never really knew what I would come home and find. I took much of that fear with me into adulthood and thought that alcohol was the only way I could deal with it.
The important thing now is that you and I know better. We know that there is such a thing as the Adult Child Syndrome and with knowledge we have the power to change it.
Learn as much about the condition and how past experiences may be affecting your life today.Working with a counsellor might help.
