Sick during the leaving cert !!

I’m literally throwing up from the stress of the leaving cert, as we are all literally stressed it doesn’t make me much different from like literally everyone else sittin theirs, but I woke up literally throwing up at 5:30 in the morning, I’m so nauseas all the times that I can’t eat meals, and I’m terrified that I’m going to throw up during my exams today, what do I do?
