I really sympathize with you all who had ''traumatic'' events in your life. My half sister is dealing with this now, rejected by her parents, being abused from 5 to 9 years old, in jail now. I got into drinking in a sneaky way. Drinking in my family was a happy event. We drank when we had party, celebration. As a French person, it is common to have a drink with dinner. When I moved out, I found it cool to have wine for dinner with my husband. The thing is he was always late for dinner so by the time he got home, I already had one bottle making dinner. I always had a lot of tolerance to alcohol so he never realized how much I drank. I guess for me drinking was like smoking or eating, the more you smoke and the more you eat, you just get used to it. It became a crazy habit, spiralling into abuse.
Don't get me wrong. My mom did the same and some of my siblings so now when I talk with them on the phone, I drink fast and a lot. I realize I am very lonely and it certainly does not help my drinking. At the same time, I decided, after 10 years, I was going to meet someone to live with, even tried internet dating. Met a few ''jerks'' and decided to stop. So still lonely and talking to the walls. lol
Unfortunately, walls do not answer back, neither do my cats. lol
