Tired Exhausted Drained

Well all the adjectives that mean "tired" apply to my state today. I have never been this tired ever after working for just 8 hours a day without any breaks. This Maryland crap is draining all my energy. I'm so tired and all I can see in the night is black screens and SQL queries. I just wish it ends sooner than later. Feel like kicking Ms. S. To worsen matters, this I-know-it-all attitude of someone. God, I want to go back!
