Hi Louie,
Welcome to SR. I'm glad you found us.
That is really scary and I'm not sure what I'd do in your position. I think I'd probably call the police and ask about the accident, because if not, it would haunt me. But, of course, you need to decide.
I also did things that I don't remember and have much regret. The good news is that you can stop drinking and regain control of your life. Do it just for today. We're here to help you.
Love, Anna
