La fatigue or WWASD?

It is getting HOT here; the saison de pluie has really made its inroads. The afternoons are starting to push into the high 80s with lots of humidity. And it is only going to heat up, according to what locals tell me. Along with a lot of work and the chaud politics at the hospital, I am totally exhausted. I wonder what Albert Schweitzer would do at this point? I think he must have frequently felt at his wits end. I haven't read his autobiography yet, but I am curious what he has to say about sustaining one's commitment to service in the face of physical and emotional overload.
