I made it through the day~~

Thanks to my "indefatigable" vigor during last night,I went through the [my]entire Friday in the [a]sleep-walking state pretending I were [was]dynamic, energetic and hard working(hard working as I am) in front of Mr.Kobayashi,[the] daunting, awe-inspiring Asia-Pacific president of ours who took over our[as] esteemed branch manager.
When I found I was just a while away*1 from the peaceful,pleasant weekend, I couldn't even believe I had almost put an end to the overwhelmingly tough day!
The whole office permeated in a suffocating,stressful atmosphere, every member of the business unit couldn't help following Koba's steps in a timidly meticulous way.
Unbearable sleepiness, complicated by the fear that all my moves might be detected and assessed by pairs of penetrating eyes, swelled up monstrously, enough to strike away my consciousness drip by drip...I was trying to remain in a relatively graceful sitting posture,whereas I felt like and kept crouching into my seat every 30 seconds.
"To hell with a working Friday~~~"I yelled out primitively a lot many times within my heart while I was still wearing a wandering look on the sluggish face of mine.
Stick to it for another few minutes and freedom is whistling my upcoming success!
Oh Holy ****! I am still tired,though. ><

*1 just a while away  this wording does not sound natural , although , "a while" does indicate time it  does not sound natural whenever it is counting down remaining time. This appears to be true because you have the action verb "was" before it.
