why am i so stupid!

i'm so easy to trust a person,
i trust that she can be my friend,
and i started to treat her as a friend.
but, at last~
what she did to me?!
started,
i really cannot treat her as a friend,
i feel that i cannot face her,
EVEN i do not want to see her!!
but~
i started to feel tired having this feeling,
why should i torment myself in that way?
why should i to do so?!
i told my mum~
when i feel that person is my best friend,
actually,
not what i expected!
i regret that,
i did something that i hurt my TRUE friend!
i have to say SORRY to them~
there was a time that i feel i so bad~
I feel that I very bad when i treat you so cold~
but,
when i saw what you did to me,
i feel that i already disheartened~
if i contineu to do this,
i just will let myself feel very disappointed~
i do not want get hurt again!
i can not afford this hurt~
after this,
i started having a phobia~
this phobia will not lost~
it will stay in my deepest heart~
why am i so easy to trust a person!
why i so easy to let people use!
what am i IN YOUR HEART!
