It is hard to grasp the concept of one day at a time when twenty years ago is eating you up and next week terrifies you and the present reality is untenable.
One day at a time does not mean toughing out every day, not drinking (or using) no matter what. If that is what it meant, I would have blown my head off a long time ago.
Recovery is a permanent thing. It means giving up liquor (or drugs) for good and for all and living one day at a time.
Most days I can live in the here and now. Before, the here and now was uncomfortable. It was always about somewhere else down the road. Or trying to forgot something from the past. Sometimes it was trying to recapture a bit of the past.
There is One who has all power-that One is God, may you find him NOW.
