I wish i could forget

I'm trying to forget the things happen last night

but...

the words you said
the way you said me

it's totally make me feel sad
actually not sad
is I feel so disappointed.

When I thought i forget it already, but it still keep flashing in my mind.
Everytime I think of it, my eyes will start tearing.
I can't control it, I'm too weak! Can't I be tough?
