It's Sunday, This time I need to prevent the panic

So it's Sunday. I'm wasting large amounts of time freaking out about this lesson on Africa, instead of getting the lessons done. Every lesson I deliver may not be the greatest lesson I have ever done, and I need to accept some mediocrity in my work. I don't think Africa is interesting, and that is largely because I know little about it. I felt in my youth Global history was not taught well. I missed many of these units as a child, so I lack the background knowledge. My co-teachers are not on the same page as to how much time I need to spend on each section of African culture. I must do what the demanding older lady wants me to do, since she drives the ship. Again, I feel so unsupported in this placement. I have been told the countries that I will teach, but no clue as to the important information. I guess that means I better consult the New York core curriculum. What's been strange, is that what these women are teaching doesn't always follow this curriculum, ending up as another situation of "do as I say, not as I do." I am shocked at the lack of organization and curriculum planning for two women that have been teaching global I for a while. How could they not know what they are doing? I am looking forward to a new placement. Hopefully my next teacher will be more of a professional, and treat me in a way that is reasonable. It is so unreasonable for these women to be so demanding of me when they don't have a clue what they are doing and do not represent the amazing teaching they expect from me. Everything they tell me not to do such as lecture the entire time, they do, so I have not had a good role model to follow.
