is it possible?

Can you make yourself sick with stress? I have no doubt that stress is the reason I have been feeling crappy for the last few weeks. Last week I came home sick a couple days. And today, I came home too. I went in and after a half hour, I had to leave. I think that today is mostly because of my period. I have TERRIBLE headache. I am dizzy. I am nauseous. I tried taking calls, but I could not even think straight. I am going to sleep now. We have the show tonight and I have to feel better for that.
