What is the conclusion of Diana's and Dr. Madden's disagreement in Act 2, Scene 10?

In a reprise of "Catch Me I'm Falling," Diana and Gabe both resist the idea of both more talk and electroshock therapy. Madden continues his efforts to convince her to try again, but Diana insists there should be no limit on the amount of time she can be allowed to grieve for her child. Madden makes one last try, but Diana leaves.
