i miss my sis a lot ~~~

the day before yesterday, i dreamed about my sister. saw she waving her hand to me just like saying good bye to me. after i woke up, i cried. whenever i think of her, i feel really sad and cried non-stop. i really miss her a lot and a lot lot lot~ today, in class, i lost control again. i cried infront of my friends... i really hope that i can control myself, but i failed to do that...why??? it is just a simple things. my emotion was really unstable today. i started to cried suddenly and thinking non-sense. sometimes i feel really suffering and need someone to talk to. but somehow when i try to talk to someone, i just can't speak out. maybe because i scared my friends will feel it is very irritating... that why whenever i feel like going to burst, i will start blogging. in the end, my blog was full with sad story~ T.T
what should i do to let my life better and happier??? this few days were really tiring me and i really give up in everythings. but no matter how, i still have to pretend to be ok infront of my friends and settle all the assignment..hope i can cope in my study and be a happy girl....
