Glad you are back noneever. Certainly a DUI is a very serious thing, and you'll likely face some financial and legal punishment. That does not mean your life is over by any means though, there are ways you can pay your dues and make it a thing of the past.
I think it's great that you are seeking help in many different areas, that's very important. I also get why others are suggesting that you don't use this as your sole motivation for quitting. As bad as the DUI seems right now, the pain/fear/anxiety will wear off eventually - and it's happened before where people end up getting a 2nd or 3rd DUI even after swearing off drinking forever. Not suggesting that will happen to you, just pointing out that it has happened and people just want to help you remember.
I think working with a counselor and coming here for help is a great plan moving forward.
