One of the things about emergencies is that you might not be frightened
while the emergency is in progress. You are so very busy just handling
the plane and everything else that you forget to be scared, too. The
whole idea of training for emergencies is to so make you used to
dealing with them that when an emergency occurs the training just takes
over.

I have flown within a mile of a funnel cloud, lost thousands of feet in
a microburst, flown through embedded thunderstorms, been rolled clear
over at less than 600' AGL by wake turbulence, lost engines to oil
pressure and hail ingestion, had a life raft wrap itself around the
vertical stabilizer, and many other adventures. Hard to say what was
the scariest moment, except that none of them seemed scary until the
next day.
