Welcome. I'm pretty sure most of us understand exactly where you are. I sure do. And even now, after some sober time, past events will pop up and I cringe....then I remind myself, I never have to do anything drunken and stupid again. Provided I don't drink.
For me, the best way to deal with the shame of my behavior is to own it. Not catastrophize or assume I know what others are thinking of me. Own my part, apologize. And work each day to prevent the behavior from ever happening again. And mostly, forgive myself and move on. I remember that, more than likely, if I was the sober one and witnessed a drunk acting insane, I would simply feel sorry for them. Don't let this hold you in shame. Own it, deal with it, move on.
