Mtn, I'm not sure what to say here other than it is good of you to reach out...a very necessary step, IMHO. Although your legal situation is serious, it could be much, much worse. It seems to me that your humility must lead you and direct your actions. Perhaps the judge will order you to enter treatment, go to meetings, or seek counseling. Embrace these consequences with everything that you've got and see them not as punishment, but as the potential salvation you are looking for.
I could not get recovery until I admitted that I could not do it on my own and was willing to do whatever it took, whether I wanted to or not.
Best of luck tomorrow and let us know what happens.
