sometimes i think why happiness is so damn hard to achieve? or does it depends on your perceptive as well? hmmh staying in library all day makes my brain becomes blur and my mood unpredictable.thinking of some past memories and decisions ive made, and made me all soppy and nostalgic, regretful and yet thankful, smiling and teary-eyed at the same time. not very good when all i wanted to do now is focusing on how t cell travels around your body and kills all the pathogens.. and just now i actually fell asleep right after drinking a can of redbull!
