Have you ever gotten so sad/stressed, you actually got sick?

I'm not speaking of depression or anxiety, but you know how elephants can die from heartbreak? So, can we, for example, get a fever from being sad? // I was speaking with my mum last Christmas, and she told me about how when I was in pre-school, there was a party at my school for Mother's Day. We had a play and food, and little gifts we made, and all parents were present. I was either 4 or 5, I'm not sure. Anyway, my father didn't come to the party, and my mum told me I was so sad, that I actually got a fever during the party. That sounds ridiculous to me, but has something similar happened to you or someone you know?
