Welcome to SR, you took a huge step posting on here, It is scary. My story is similar to yours,, I have a great life, 2 great kids, a beutiful home a sucessfull buisness. But drinking has always been a huge part of my life. My husband also drinks, but doesnt ahve aproblem, we used to drink a few beers everynight to unwind. After a while the beer wasnt enough for me, I started buying bottles of vodka and hide them. I would stay up late and drink. He didnt know until I told him last weekend. I feltl like a huge weight was lifted, I didnt have to hide anymore. He was very supportive and doesnt want alchohol in the house anymore. I also went to my Dr and told him everything. He is helping me with the withdrawal and gave me some meds to reduce cravings.
The best thing you can do is be honest with yourself and your loved ones. I dont have a sponsor, but I have the best Pastor in the world who is very supportive and I can call her anytime. Good Luck
