I figured I needed to give myself some time and then I can approach it with a clearer mind. Looking at it today I definitely feel better about the new duties. Mostly I see I will need to be that person in the middle who communicates and negotiates requests. There are some major duties to take care of, but I think there will be time to understand it all.
Mostly I just hope I will have enough time to set up my new room, including rearranging the teacher's desks and putting away all my materials. That first day back is a full schedule of orientation meetings and greeting new students. I kind of wish they would give us more time to set up.
I managed to have some free time today to look over my upcoming work for next semester. I recall how before the semester ended, a few weeks ago, my mind was blown by the team leader stuff coming my way.
