It sounds to me like you are going to be receiving quite a bit of specific care through the community program and the therapy, correct? If so what your GP thinks shouldn't matter all that much as you are already approved for that program right? I'd focus squarely on that now if you can. I'd very seriously heed the warnings given about the ramifications of drinking again...this is literally a life or death situation for you. Especially if a binge of less than one day caused that severe of a reaction.
