If you are really ready to quit, it won't matter what other people think. Set aside that fear of being judged. You don't have to go around telling people anything you don't want to. I told pretty much everyone I knew I was having serious problems with alcohol and needed to quit. I told a few people close to me that I'm an alcoholic. As time went on I became more open about being an alcoholic, but you don't have to explain anything to anyone if you don't want to. And really - very few people really notice or care. Only those close to you will care at all, and I'm betting they will be supportive and understanding.
