Welcome, Mrs. Brown!
This may or may not be you, but I used to be a very social person before I started drinking heavily. The drinking made me very ANTIsocial and made me isolate myself more and more. When I stopped drinking, I figured out that I was incredibly lonely and even though had felt that my isolation was a "choice," it really wasn't ... it was the alcohol that did it to me. I started going to AA, started making sober friends and doing social things with them and to my surprise, I found myself really enjoying being "out there" again and being sociable.
Solitude is one thing ... isolation is another. Solitude can be a good thing when the time is used positively. Isolation, especially to the alcoholic, can be deadly.
Whatever path you choose to get sober, I wish you success on your journey. Glad you're with us.
