Hi and welcome,
Having started working a 12 Step programme in OA back in 1999, I found myself relapsing a couple of years ago with my latest addiction which was alcohol.
I know exactly how you are feeling. I was ashamed because I should have known better alongside self-loathing and guilt. How could I face anyone at a meetings, people I have previously sponsored. I was a hypocrite. Note : Ego talking -
I should have known better.
None of that matters. I've been welcomed at meetings with open arms. No-one has judged me. I've been on my knees admitting my powerlessness and working the 12 steps again. It feels great! Recovery is great.
Plenty of support here too
