Only thing you can do is learn from it , you can select some positive aspects from your 11 days and move on NOW , capitals deliberate as we only can live in the now , the past is past end of .
A day at a time living our life and keeping away from the 1 st drink is advice every recovery movement on earth recommend , I am sober over 9 years and yet I am on the same footing as you ,we are both one drink away from a drunk , ok I have more experience than you at present but I did exactly the same as you , I was sober 22 months and lifted a drink so you can give me credit for ''knowing how you feel to lose some sobriety time '' most of the successful people on earth made many mistakes , but learned from them ,so toughen up start again with new found determination , take care .
Regards .
