Dean, Gee, that's a difficult one. I'm not so sure what to suggest. It seems that she knows there is a problem, but choses to ignore it.
What would happen if things were to stay the way they are? Would you still want to stay married?
You could tell her that she needs to at least make an effort if she wants to stay married.That you need her to fill out the form your counselor gave her and to see a doctor for tests.
Of course if she refuses you would have to make the choice whether or not you could live with things the way they are or not.
I think your counselor was remiss in not seeing that she followed through on the questionaire.
Just my opinion...Hopefully somebody else has some more insightful advice for you.
