"You're being paranoid" is a common phrase in everyday language. Anyone who's intensely uneasy about something, especially when there's little reason, might be told he or she is being paranoid. Take an employee with a good record who is really worried about an upcoming review, or a person who wants to leave an hour earlier than necessary for a concert saying, "I might have to drive around for an hour to find a parking place." Friends might well say, "Quit being so paranoid" to these people.
