He had a problem with you drinking four days ago... wow.
The nerve.
I guess he doesn't understand his job description and his role in your recovery. Nor does he seem to have a clue about ethics or responsibility.

And most importantly... do not focus on this issue or let it stop you from getting the help you need right now. Go on and get yourself a new counselor if you can while you're there.
