A big hurdle for me was somehow accepting the shame and guilt and regret and the garbage of my past, and accepting the fear and uncertainty of the future. I was really terrified to think of a life without alcohol. The answer was to keep turning my focus from the depression of the past and the anxiety of the future to the present moment, that moment in which I had vowed to not drink. I used mindfulness to help with this. You can find lots of information about mindfulness and addiction on the web.
Try to remember that there is a brand new person inside you now, bruised and frightened. This person needs you to look after him, to protect him and care for him. Be kind, and generous, and understanding. He will grow and mature and be respected by himself and by those who love him, and you will be so very very proud. Onward!
