2010 Is A Bad Year For Me

Things Has Ruin My Everything In Sudden And any without any reason.The one that i trust the most had betrayed me .. I really don't know why she wants to do that to me ... I have nothing to do with her .. What i dont like about her is , she likes to express out her sad face everyday .. Then when i care about her and i ask her what's going on , she doesnt wanna let me know .. When i tell her that dont be like this , she tells me not to care about her .. What's the matter ? She knows how to say that why she wanna angry also have no right to be like this then why i dont have the right to care about her ?? Being a good friend will care about you and when there's problem , will share together . but she DOESNT !! Being A good friend will tell each other properly what's the bad attitude .. and will happily change it .. it's not like because of a small problem then get mad of it .. IT'S NONSENSE ! I have done everything but what i get at last ?? I don't know how to treat a human being anymore .. When i'm good , they said not good enough.When i'm Bad , they will say it even worst .. What SHOULD I ACTUALLY DO ?
