Sunday Night Anxieties

I don't know about others, but I know that on weeks that have a huge amount of deadlines or project gates, I tend to get anxiety on Sunday afternoon/evenings. Some may take it badly, but I have managed over time to use it as nervous energy to get more done. To me it represents that I still am passionate and dedicated to my goals and won't accept any mediocre performance from myself. Am I alone in this weird emotion lol?
