I’ve met many people who behave in the way you described, some suffer from various types of anxiety disorders. I work with a few and have some in my family and so on..
Let’s say a person without anxiety disorder would be ok sitting down thinking what happened to the package. Person overwhelmed by anxiety cannot tolerate anxious feeling of unknown and must immediately do something to ease the anxieties by acting/saying/doing based on emotion.
That’s where motivational reasoning comes from. Life is full of unknowns. But people with severe anxieties cannot handle unknown. They prefer to act right away or believe in some erroneous things so they can have certainty (even if it’s completely erroneous).
Have you been ever diagnosed with anxiety of any sorts?
