Welcome onmyown. It can certainly be scary to admit your problem, and there are places like SR where you can get lots of support and remain anonymous. There are also other methods like AVRT and other self-paced methods that you can learn about here.
Having said that, most likely your husband already knows you have a problem. As addicts we think we are hiding it well, but in reality it's impossible to keep it from those close to us. They can smell it on our breath, they see how we act when we are drinking, they see the financial impact of the money spent, they find the empties, etc. I personally could never have gotten sober without telling my wife and getting her support. I didn't share it publicly but to me hiding my recovery is nearly as bad as hiding my drinking.
