Continue to be a friend.
Even in the most extreme cases where
the other refuses to take responsibility and seek help you may
need to communicate:
"I'm not equipped to give the help you
need, but I will stand by you and be your friend."
In extreme situations the "troubled" chaplain may need to be by-passed
in order to get him/her help. In such cases, make a direct appeal to
the appropriate person (usually in the technical chain), but only when
personal efforts have failed, and as a last resort.
