We should smile or not?

We have found my teacher already. Her dead body is at Pang-nga now. We will burn her on 29th September, I can't go because I have a final exam. I want to go. She is my teacher!! ... anyway we have to be happy don't we? because we found. And she could be in the heaven in peace....

But it shows that she is really died and will never come back again. Should I cry? I am always miss her. Please tell me. :'(
