Tired of everything

These semester, I very tired physically and mentally.
I was chosen as the class representative.
These few days, I was totally worn out physically and mentally.
Yesterday, I have class from 8am until 9am, then follow by clinic from 9am to 1pm.
After a short 30min lunch break, i continue my class from 1.30pm until 6pm.
So unfortunate that my library duty from 6pm until 12am.
Basically, i was busy from 8am until 12am.
16 hours...
It just the beginning of my semester...
I scare Monday the most, if no libray duty it would be from 8am to 6pm.
As a class rep of the class, i need to settle the BIG issue that i faced was the timetable and the clinic hours.
I got two forces that tearing me apart, one is the student wanting for fair whereas lecturer want to stick to the plan timetable.
I was mentally exhausted for thinking to settle two contradicting issue.
I hope everything can be settle asap.
God, i put all this issue unto You...

I can do everything through him who gives me strength. Philippians 4:13 (NIV)
