I have a 7 year old daughter who has an anxiety problem. When she gets over excited she pukes ( gross I know ), but in our home we make no big deal over her getting sick in the event that something exciting is going to or has happened. In the past this happened all the time like 5-6 days a week. She has been to a counsler, and is down to hardly ever throwing up unless the situation is extremely exciting. 
 
My problem is this. I have talked and talked with her teachers and the nurse of the schools, and it has done me no good. Like yesterday for example the school was taking a field trip to visit the local Caverns which is really exciting and of course when my daughter got to school she threw up. The school calls me to come check on my daughter ( which is 100 % ok ) the problem is when I got there they wanted to send her home. I know for a fact that my daughter was not "sick sick" she was just really excited over this field trip. I told them her throwing up was " no big deal" and that she was alright. The secretary and another staff of the school where standing there and of course got this " omg you horride mother" look on their face. The woman who I don't know who she is was like " she needs to go home shes peaked and pale" WELL DUH she did just puke.  
 
The end result was my daughter was not allowed to go on the field trip unless I fallowed the bus down in my car. I don't drive so this was not an option. So of course I got to be the bad guy in it all because I was the one who had to tell her she couldn't go. No one at the school would let her go including the teacher who I explained the throwing up thing too.  
 
My question is this. What am I to do, if the school sends her home over her puking during exciting events at the school, my daughter is not going to be able to participate in any school funtion weather it be a school field trip or school parties. I don't want my daughter to be known as " the girl who pukes" and as long as the school makes a big deal over it the more it will happen. How do I get them to understand? There is more to the whole thing but I don't want to bore with every detail. If someone has any words of advice it would greatly appreciate it greatly.
