Time to start digging out. One day, one hour, one minute at a time if necessary.
People from your past, if you can mend things with people someday then good, if not then I guess they are not part of the new plan. The next chapter.
String together a few days sober. You will be starting with a blank sheet of paper. New hobbies, new interests, find out where this road leads.
Maybe for now eat some ice cream and try to find something on you tube to distract you. I'd probably pick something dorky like some history documentary or something on cars or football. Sometimes stand up comedy passes the time. Maybe some AA speakers could inspire you or something like that. For now just try and grind down the time. Get some distance between you and that last drink.
