Just Being Curious

I'm in my second school year of being a Paraprofessional in a Self-Contained SPED class. I absolutely love my job and my lead teacher is one of my best friends, so my problem isn't in that area. My problem has to do with the fact that I don't get a break... I'm with students from arrival until dismissal. We have to eat lunch with our students, escort them to Encore classes (I don't have a problem with this)...some days, I barely have enough time to use the restroom. Am I alone in this, or are some of you experiencing the same thing?
