Giving up any addiction is scary let alone any attachment. I remember being terrified the first time I left home, when I joined the army, my first "action", when I left the army, getting married, waiting for my two kids to be born, before going into surgery to remove a tumor in my head and finally hitting rock bottom six months ago and admitting I was powerless over alcohol. The fear I felt has spurred me on instead of making me freeze and give up. Use that fear to your advantage, turn it into hope and strength. Its OK to be scared, courage is the willingness to act despite fear.
