I missed work today, because I couldn't sleep. I came home yesterday with a huge headache and went to bed early. Unfortunately, I didn't sleep well at all and I still have a headache. I have been extremely stressed out at work this week with the absence of my Co teacher and yesterday at work I was freaking out, because I had to be prepared to present an activity for the Cinco De Mayo celebration to the parents at the agency that I work at. I didn't realize that I had to do this even though I had the activity all created and with the absence of my Co teacher, I was freaking out even more about doing this in front of the whole school! I just thought I was supposed to just do the activity in my classroom. Apparently, all of the classrooms had to do this. I have been written up for calling off too many days already. Now my supervisor said that I need a doctor's note. I don't know what to do now.
