stressed

My stress level is really high today.  Just a lot of little things adding up.  I do not have any time to plan lessons or organize myself and try to figure out what I'm doing.  There are so many things I feel like I can't do and I know I'm not doing a lot of things that I am really supposed to be doing so I am definitely going to get into trouble.  Teaching eight classes a day is too many classes, and not having any books to teach from and even after three weeks here still not knowing everyone's names 100% is making me crazy.  Usually I am ok in Japan but today is one of those times that I really just want to go home.  Just feeling extremely anxious.
