i guess i'm really tired already. i do not know how long more can i stand all this crap. and i really feel like withdrawing from this project. i really do not have the time and energy to do it anymore. end of year exams are coming, they are my first priority now. but still, i'm stuck with all these. i should not have made such commitment at first. i really regretted. had a maths marathon today. had both a and e maths tuition on the same day. quite restless for the last half part of the tuition. but i told myself that i have to hang on. for the sake of myself and my exams. my eyes are shutting down. and he's very ill. really make me worried so much for him. =( i'm really tired.
