A stressful but rewarding situation

We had a very occupied lesson which requires us to understand and memorize terms for our quiz at the end of the subject. I quickly memorized terms but my energy is consumed and head ache is felt. The quiz started at 4:50pm and I answered most questions surely. I am rewarded with a score of 13 points over 15. After the results was given, we were dismissed but as I arrive in our house I am sweating profusely. I believe that the sudden diaphoresis is the effect of lack of vitamin B12 in the body due of its excessive use.

I am a bit sad that I sweat profusely but at least I realized that every action has a consequence that may be good or bad.
