I had the same thing happen a week ago. I'm happy for you. Be happy for the now. One thing I tried to remind myself and still do daily is tht it's just the beginning. It's a huge step but it doesn't mean everything is magically changed. Be proud and be happy but remember to take one day at a time. I wish him the best in his recovery! I'm very happy for you that he is taking this step!
As a side note-I reccommend searching for one of te best rehabs. My rabf is at one that he doesn't feel is doing any good. They aren't meeting wth individual counselors-and very few group meetings. He is getting very frustrated. When he decided he wanted help he wanted To go and get started. That meant calling a hunch of places that came up in nj from google and seeing who had space to take him ASAP. If we could go back we would do more
Research on the best rehab he could get into. Just wanted to share our experience so hopefully your ah can get ito a great program! Best of luck!!
