Just to much!

My job has just become so unpleasant . I keep trying to push through, but I feel like I'm not going to make it. It's like ground hog day except I can't figure out how to change it to make it better.  The main problem is that I see most of the same kids over and over again, but there is nothing wrong with them.  I'm not talking about kids with chronic illnesses, like cyctic fibrosis , diabeties, sickle cell  and asthma. Those kids have to come to the nurse for treatments and if the are having problems. I like taking care of those kids and helping them.   Most of the kids I see have no reason to come to the nurse 30 times in a year. Really I can't even tell anymore if they are sick, I just have to go by if they have a fever or they are vomiting.  And the true problem is, if I have so many frequent flyer kids in my office and I'm trying to help a diabetic, I could make a mistake. A mistake with a diabetic could be life threatening.  But no one understands. I've sent email after email about frequent visits. I write on their pass, "this student has had 25 visits to the nurse this year" .  My boss came and talked to my principal telling him that I have see the most visits this year of any school in the district.  Nothing changed.  I think I'm going to go talk to my principal this week and tell him of the changes that need to be made. And if I can't instate them, then I will need to go get a job else where . I don't want it to sound like a threat, it's just a fact. I've become so unhappy. Every Sunday I already dread going in the next day.
At the end of yesterday I had a parent call me and bless me out. Her husband picked up their child and said I was rude. Truly you guys, I don't feel I was rude. My office was very busy. Could he not see all those kids in my office??  I gave him the slip to take to attendance. I told him he needed to sign her out in attendance and to leave the slip and that excuses her for today. He was rude and harsh with me saying, "we'll where is attendance?"  In a mean tone. . I asked his daughter if she knew where it was, she said yes. I asked her to show her dad. ( it's right down the hall from my office ).  I told his wife that my office was very busy, I didn't mean to be rude if I was. I told her I was trying to take care of  a diabetic and lots of other kids. She goes on to ask me if I didn't think her kid was sick and her daughter has migraines. Nothing written on students health card about migraines or any other illness.  ( the last two times I've called her mom, one for an ear ache and another time for a headache , mom said the student would just have to tough it out.)  I'm not sure what was different about today. Mom just went on and on. I really don't know what she wanted me to say. I just said again that I was sorry, I didn't mean to be rude if I was. Ugh!!!
