I don't know enough about the topic to judge most of what you've said, but I can appreciate something about your final point and something you suggested in a later comment: most people feel anxious about meeting someone, going to a new place, interviewing, presenting in public, etc. Or they put off work without a deadline. These are common and largely modern problems.

We might be able to revise society/expectations to address this, separately to how we diagnose/label problems.
