Go easy on yourself Sark. I have had relapses in my short career as a non-drinker and member of this community. All I can say is pick yourself up, and try again. There is no shame in that. The only problem I see going forward is if you don't commit again. If it was easy, this beautiful place wouldn't exist. :-)
I would kindly suggest not to worry what others think right now. Your sobriety isn't about them, it is about you. Worry what YOU think about you. And if you re-committ, make a plan and stick to it, I imagine you will think pretty highly of yourself. :-)
So keep on keepin on. Today is a new day. And if you ended up at the bar, make it your last trip. You can do this. We are here to help.
Blessings.
