Am I made the wrong decision??

Last week my sem 3 results just release..
I don't know how to say on my results
I'm totally get shocked when I saw it
For me, it's impossible to get suh BAD results..
That night, everyone are posting in facebook
Some of them said:"hardwork had paid,thanks god"
Some said:"satisfied"
But what could I say that time???
I'm speechless when saw that on facebook and quickly switch off my computer..
I'm not dare to tell my parents even my brothers also..
I'm keep thinking and thinking...
How come it became like this...
It's unbelievable...
That time I was thinking of maybe mpm will giving wrong result if checking through sms..
But when I check through internet on the next day
I really cant say anything...
I only can said that
Maybe my hardwork is not enough..
Maybe I'm lazy that time...
I can't blame teachers, can't blame families, can't blame anyone
The only one who can blame is MYSELF...
Well...not only me get such bloody results
I think most of the science stream students unsatisfied with mpm
Now when we're seeing each other
The questions they will ask are "How was your result?"," Have you retake?"
Oh god...
I had heard and answered this many many times already...
One of my friend had ask me "have you retake"
When I told him "NO"..he was saying me Siao Zha Bo...
Why??? Why saying me crazy???
Is it I must retake??
Sometime I don't know whether have made the correct decision or not...
Sometime I was thinking that if I retake can I get the good result?? Is it enough time for me to study?? Can I pay more hardwork on it?? Can I finished study in one month time??
I don't know...
My mind is blank when think of retake...
I really wonder that is it wrong decision I made??
