unforgivable

maybe i just expect too much,
overall it is ok,
but why am i feel so umcomfortable now?
i know i can do much more better..
i know if i given more time..
i can find the answer..
but why..??
i just couldnt calm my heart down..
i couldnt forgive myself for the mistake..
it is so unforgivable..
i know i shouldnt stay at this point of time..
but..
sigh...
