Good luck to you. I am just finishing up my first day of sobriety here and am only trying to focus on making it through portions of the day, not thinking about the rest of my life. I get so overwhelmed and well, if I'm honest, sad, about thinking about never drinking again. But I know that once I am more clear headed I will come to be less sad. So for now I just try to make it until after lunch, then I think about from lunch to dinner which I my most difficult period, then I just need to make it to bed.
I also have two young children and they are a great motivation for me to get my stuff together before I slip any further towards rock bottom.
