I've got nothing to hide and actually find it to my benefit to call myself an Alcoholic but I can understand the vilification you must feel if people are judging you solely based on a bad habit.
People close me to know that I have this problem and will discuss it with me if I seem to be struggling. Before I was ready to quit though, I did have some snickering in my direction because of the booze.
Just remember, regardless of what others say you are quitting for you and only you. Right now, when it comes to your health only you matter. If you try to quit because others want you to you will only feel resentment towards them as you try to get through cravings.
One day at a time right now and you'll be able to walk tall into that next family encounter and be proud of yourself.
