If I guy drinks too much and his liver or other internal organs stop working correctly, you would say he has liver disease. But if he drinks too much and his brain stops working correctly, then its just a choice? Sorry folks, the brain is an organ just like all the other organs in your body, and whether you like it or not sometimes it doesn't work right. Somehow folks believe that everything is a choice but it simply isn't. When you get addicted to some substance, especially a legal one like booze, its just that...an addiction. It removes the "choice" part from the decision. Depression, anxiety, and other disorders of the brain are real things, no different than a heart valve that doesn't work right. Sadly, its amazingly common and almost always simply dismissed as not being tough or disciplined enough. You can't just "will" yourself out of an addiction or depression any more than you can "will" yourself free of cancer.
