Sorry to hear what you are going through. My boyfriend who is now 7 years sober had the same thing happen to him. He had a 2nd DUI at 22y/o and was looking at jail time. Through the suggestion of his family he decided to enter treatment and that completely turned his life around. All of his legal problems worked their way out and now he is living a productive life. I understand you mentioned that you were in debt and about to lose your job but I'm sure there are some more affordable treatment options in your area if you decide to take that route
Wishing you all the best, stay strong
