Do you keep calm in a crisis?

Sometimes I can keep calm on the outside. However, inside there might be absolute chaos. Then I throw up and I can move on from there.
There was that one time that my kid broke her arm and I fell apart. My mom had to tell me to quit screaming. It was freaking out the kids. My daughter with the broken arm told me that I needed to calm down while we were in the emergency room. Of course, I think I was laughing. Maybe she thought I was really losing my grip on reality.
It doesn’t sound like I deal with crisis situation’s very well. So maybe call me after the crisis and we can discuss it over coffee.
