sometime i wonder whether i'm selfish or not... its seems that i only can see my own problems and relying the rest to listen to my problems. though there was no complaints from any of my friends but i feel that i'm selfish.. self centred. i know that it has been a tough time for me for these few months and i'm too focus in his and mine issues.. and i lean onto my friends too much.. it nv comes to my mind that they themselves also facing a dozen of problems which were unknown to me.. but why do i have the cheek to rely on them.. they are not obliged to listen to me.. why am i loading with them my problems. i'm not that kind as what other think too.. self centred and selfish are all i can describe myself now..
