Preschool = Thrown Back

Today was my first day of my field placement and I am at Covenant Presbyterian Preschool. I went this morning at 7:40 and tried to find where I was supposed to go but there seemed to be no one there but at like 7:50 a teacher by the name of Mrs. White walked in and told us we were in the right place and continued to tell us she didn't know why they didn't tell us but they don't start until 8:30!!! Which is great for next week! After awhile of looking around the three classroom would could choose from we had to decide if we wanted out of the 3 year old, 4 year old or Kindergarten. I chose the 4 year old with Mrs. White since I felt like I had already gotten used to her room (from being there so early) and she seemed nice.
The kids got there between 8:25-9:00 and they all have such distinct personalities. I could tell which was the baby, which was the leader, which boys didn't get along, etc. all within them being there a total of 15 minutes. The schedule is
play from 8:45-9:45
clean up 9:45-10
outside 10-10:30
calender/snack time 10:30-11
puzzle time/reading time 11-11:30.
I enjoyed my time there but decided I don't want to teach Pre-School. I loved observing their interactions and reading book after book to them (esp. when they all wanted to sit in my lap) but I want to teach older than that.
So...by the around 10:30 my back was suddenly killing me. I didn't understand. This morning when i woke up it hurt but i just figured the weather was changing or something...but by the time i got to my car my back was completely gone. I couldn't even lean forward to turn the air conditioning on. Its an awful feeling to feel so helpless. If I tired to bend over or slump it felt like my back was pinching and an awful pain shoots through my whole body. This has happened one other time and all i did for 2 days was lay in bed and do absolutely nothing! I don't have two days to do that! Hopefully today will be enough. When I got home I changed back into my PJ's, crawled, slowly, painfully into bed, watched TV, took a nap, read some, did everything I could possibly do from the bed and now I'm bored and still in pain. Oh well- Life Happens and I'll be fine before you know it!
