Hi...I teach KDG, as well and I can totally relate to what you are saying. I start back on Weds. the 17th and we have students on the 19th. DH knows to be very considerate of me the first few weeks of school as I am exhausted at the end of each day and, after having been oh so very patient all day long, I sometimes 'lose' it in the evenings! LOL
I see you are in IN, as well as me. Sure hope your school has air-conditioning!
Good luck to you during these first few weeks of school!
