Affliction, it sounds like the AA meeting you went to was not quite where you are yet. You should look for beginner's meetings. Often at those meetings they have individuals who are much further along and are available to new comers to be their sponsors.

You do need support, and you also need to take it one day at a time and focus on staying sober each day and taking care of your children and working your job. As far as your wife is concerned, you have to let that go for now and focus on YOUR own effort to get sober, reaching out for support and literally taking it one day at a time and often that includes staying sober an hour at a time in that one day.
