not feeling well

This morning not feeling well, because when i wake up at 6:30am my head was very heavy and pain then i continue sleep until my mum called me. Recently i sleep early before 12am but still can not feeling well, wonder what the problem that cause me feel not well? Whole day my head very heavy and pain, feel like no energy to do anything luckily today i do not have any class if not i don't know how am i pay attention. Yesterday i having class on evening, then i was run from the car park till the class because i seldom late to class and i worry the lecturer was in the class, lucky he wasn't there and not only me late to class. After finish the class i only realized raining and i didn't bring my umbrella so have to run to my car, end up my bag,pant,hair and shirt was wet. Then i have to pack my dinner alone, when i reach home i was very cold and quickly changed my pant and shirt. I feel very tired after finished my dinner but i still bear till 10:30pm only go to my bed and listening song until i sleep. Perhaps after this chinese new year i will become very busy, because i know my quizes,mid term,assignments,replacement classes will come to me after chinese new year, so now is the sweet time for me to relax and keep my energy after that my panda eye will appear hehehe...That day i read one of my friend's blog, even i not very close with her but i realized that she changed. Maybe the changes of her is good, perhaps she can live happily and appreciate whatever she having. I remember got a person told me before, he said he couldn't understand me how come i can change my mood so fast yet he also realized that i changed. He told me that he miss the girl that he know before not the one had changed. That time i was asking myself silently is that worth? my changes is good for me or bad?
