Awful feeling

I can't even begin to explain how awful I feel. I feel nauseas and I have a headache. Why am I always sick? It really scares me. I can't even right now. I want to go home but I don't want to do that to my coworkers. But I feel awful, I don't want them to think I'm another Erin who fakes sick. I'm going to try to eat something soon.
