I am glad that you posted... you will not find a more supportive group of people to help you, if you are really searching for it.
I can say that we have all been there... we've all had to tell our family members so that we could get help. Now... did we have to make an announcement at the family reunion? No... you can tell the people that you think need to know and that can help you and be the most supportive people. But first... if you aren't comfortable with this... why not start looking at your options as far as assistance is concerned? I know you are feeling overwhelmed, and that's normal. You just have to take baby steps until you are ready to attack this illness head on. And when you are ready for that, you will not have to go it alone.
All of that being said... you've made a tremendous accomplishment by coming here... I know that I did when I first posted.
My experience w/alcoholics has been this.... my dad is one and he does the AA thing and it has worked. He hasn't had a drink in like 19 years, or something like that. In addition, my sister was extremely bad and she just quit - all by herself... started exercising... got on the right anxiety meds and anti depressants and she's doing great now. She's gone almost 7 months now. She did not go to meetings... I still worry of a relapse because of the fact that she does not seek support on a daily or weekly basis. It's scary... But... so far she's been extremely successful. Believe it or not... the first 90 days are the worst. And then she said her cravings were basically gone.
So... you are not facing the impossible... even though you may think you are. We are all here for you and please let us know how you are doing. Take care and we are so happy that you have joined us. You will not regret it.
