Sorry to sound cynical but 'duh!'. But I'm sure she'll (the therapist) be helpful to you and DS.
It must be a worry about his threats to drink himself to death, but it might be premature to ask for a welfare check. It can take a while for someone as addicted as he is to reach that point. OTOH he might just reach the conclusion that he doesn't want to die, which will mean total abstinence. I'm not an AA person and have never done therapy for drinking, but I know how my receptors light up if I drink, and you can't fix it in retrospect.
You're going to have a challenging time ahead - best wishes, you can do this!
