Sometimes when someone asks us how we are doing, and no one has asked that question in a long time, in that tone of voice, as if they truly care how you ARE actually doing-you cry.
You hope that they don't write you down as a head case in your charts and you move on, and you make sure that the next time you see them that you appear capable and in control.
Doctors and nurses are used to this. It's a part of the job.
