12 Angry Men

I have now had six (6!!!) students drop my class in the first week. What could I possibly be doing that is so wrong? People tell me things like well maybe a class they were waiting for opened up. Not for six people, there's no way. We've had one assignment. And yes most of them did crappy but it was a tiny-counts-almost-for-nothing assignment. And the one drop got the highest score in the class so what of that? I dread going into class for fear of losing even more of them. Perhaps if I just didn't have class at all next week I could keep the rest of them from leaving. Do they think I am an idiot? That I have absolutely nothing to teach them? I seriously just want to burst into tears every second that I am in the room with them. How can I do 15 more weeks of this? How? Should I ask that someone else take over the class? Should I quit?
