In dealing with those who are undergoing great suffering, if you feel "burnout" setting in, if you feel demoralized and exhausted, it is best, for the sake of everyone, to withdraw and restore yourself. The point is to have a long-term perspective.

Shri Ramakrishna use to say, "As Long as I Live, so long do I learn". That man or that society which has nothing to learn is already in the jaws of death.
When we look in to the long avenue of the future, and see the good there is for each one of us to do, we realize, after all, what a beautiful thing it is to work, and to live, and to be happy.
