ZARS - zombie acute respiratory syndrome

I really am concerned now. I've had a cough for about 6 weeks now. I think it might be whooping cough. But I don't want to go back to the last doctor that I saw, because I think she might be a nitwit. I don't want to go back to the other doctor that I saw there either, because I'm SURE he's a nitwit. My regular doctor is out on maternity leave. What to do?
