Where am I

Am i work too much, or too stressful today? I've worked about 9 hours today, and I still need to finish 1.5 hour at home... I feel so fancy now, that my body is like flying in the air, or my mind. Can't make sure if I'm home or in somewhere unknown. I could be in my bed or in the office chairs from my office. Blood is only enough for my half body. Cold hand, weakness coming. Don't like this feeling. What's happened to me?
