I had to do it alone. I have many friends but I had to "shuffle the deck" to get/stay sober. Okay, throw the deck in the air and play "52 pick up" if I'm being honest! Now after four years it has stabilized and the people in my life are a part of my on going self rehabilitation or at least not a part of the decline and fall of Gaffo.
I had a couple of friends who quit around the same time as me but even they will admit that we all did it alone at the same time. There's really only room for you in your own head. For me the important thing was to have faith that it would get better and it has. Coming here frequently helped me immensely, Dee74 is right (and he usually is!).
