Kris, What you're feeling is accurate. A lot of really bad things are going to happen if you don't quit. If you keep drinking you'll probably lose your family, then your health, then possibly your sanity, then your life. This disease if fatal. It's also progressive. Your drinking will get worse. And it's cronic. There's no cure. So be afraid. Be very afraid.
Now having said all that negative stuff, there is hope! This disease can be successfully treated. If you recover from alcoholism, none of this has to happen. But willpower alone isn't going to keep you from drinking. You need a support program, and I suggest AA. It's saved my and thousands of other lives. So stop with the excuses about the road to heaven and get to a meeting now. Not next Thursday, not soon, but now! Try a Woman's Only meeting to begin with as you may feel more comfortable. And if you don't like that group, find another. If you're really serious about wanting to quit drinking, stop with the pity party and start doing something positive.
Oh, and go to your doctor and let him/her know what's going on. You may need medical help during detox. And in any event, your doctor has to know about your addiction.
