Welcome to SR! You will find lots of great support on this site. You should join he August class, you will be surrounded by others who have also committed or recommitted to sobriety this month.
Blackout is a great book, you may want to read it as you begin your journey. There is a sticky that Anna posted that lists lots of great recovery books.
Also, start each day in the 24 hour thread committing to remaining sober for the next 24 hours.
You can do this one day at a time!!!
