I'm a non-native speaker, looking for a single term to describe the quality of feeling overwhelmed with a task of work in a person.
I found overchallenged on dict.cc, but when I wanted to look it up on oxforddictionaries.com or merriam-webster, I found no match. Thus, I conclude the term is not commonly used amongst native speakers.
What alternatives are there?
He felt [overchallenged] by having to carry all the bags by himself.
