What kind of pre-delivery stress does katie have to deal with

Many things like it don't make sense but since you asked:She has to deal with whatever she ordered

This isn't exactly a complete question but the stresses go as far as waiting on the package, if its an important one she has to sign for it which means she has to be there otherwise they wont drop it off, if she misses them i believe its three times she has to take the slip they leave to go pick it up at the post office, I don't know if this helped but you weren't exactly specific about what you were asking..

Bis the right answer

The answer is corticosteroids
