I can't go to the ICU!

A little background: I'm just starting the final year of my nursing program. Our clinicals allow for us to have certain observation sites are various hospital units, one of them being the ICU. I have a very strong interest in critical care and would really love the opportunity to go here during school, even though it would just be a one day observation.

So now today during orientation, as we were being handed our clinical site rotation, the teacher states that unfortunately, a conflict with another local school has lead to the ICU rotation site being removed from clinicals this semester. I'm extremely disheartened, the ONE place I was looking forward to is now gone all due to another school in another county getting the spots for its students first, or whatever happened. Am I overreacting, like I said, its just one observation day, but it was one I was REALLY looking forward to. I want to work in critical care, and I feel any way to get my name known in the ICU would help when job hunting, and one opportunity has already been taken away from me.
