1st - breathe. Then break your problem down so it is manageable and not overwhealming.
You have a desire to quit drinking. What are you willing to do to stop? You can even break it down into something smaller - What are you willing to do to not pick up a drink today?
You are in good company as alcoholism knows no racial, educational, social or economic boundaries. Anyone can be affected and this means that you are not alone, you don't have to do this alone and in fact, you shouldn't do this alone!
I encourage you to seek Dr. advice on detoxing if you plan to stop, and seek out advice and information from those who have been there - namely people on this forum, AA members, alcohol counselors etc.
Welcome and I wish you a long and wonderful recovery!
