have you ever had a feeling of being left out?

well, i had. i was quite naive to think that i will not have this feeling when i get into secondary school. but i still get them when i'm with them. i'm, in fact, very tired of this feeling because i've been getting this feeling since the day i stepped into primary school. really feel like crying sometimes. the most frustrated thing is that whenever i try to talk to them, they always try to ignore me or pretend to talk among themselves. why? i mean, why must they do that to me? i always try to be good to them but they are still like that and when they are finished, they even pretended nothing had happened! they even asked me what had happened. what would i say? of course i say nothing happened. i really feel sad because they always act like BIG SISTER. uh-huh. **puke.
