Regret?

I do not know how should i express it. Is it regret? Sad? No emotion at all?

Although it has been awhile since the UPSR results for this year was announced, i am still searching for what we call-emotion. Yes, i do admit that this year pupils were really different from last year. But all my life i believe that people would change no matter what. We have been all out this year since their year 5 result was not that convincing. Afraid, nervous, angry, sad, happy-i tried to show those emotion on that day. None. I looked at them and just looked at them, telling myself to cry at least... but nothing happen. Does it means that i do not care at all? I took care of them for almost a year. Allah knows all. They really got into my nerves sometimes. I have tried to gather all my patience to face them everyday. I even shed tears for them. But knowing that they really don't care what the future holds for them make my heart crumble. Since that, i feel like i lost hope for them. Maybe that is why i do not feel anything that day. Life is like a box of chocs huh?
