Guess what - your not alone. I relapsed, and many other people relapse when trying to get sober. We are alcoholics, we drink, it is in our nature.
The question is, what do you want to do about it? Recovery is a process that does require effort on your part. What are you going to change to lessen your chances of a future relapse? What are you willing to do to remain sober?
Try answering those questions, pick yourself up and try again - you are alive so it is not too late to stop drinking.
