Can you help me and guess the word?

I am looking for a word... Its one that I can't quite get correct. I can think of many others that relate to it, but not the word I am looking for..

What is it called when:

You expect something to happen, something that's regular and that you look forward to. Something that brings you happiness and joy and that you would be sad if it didn't happen. Well at short notice you are told that its not going to happen.

Initially you are sad, but the reasons given to you mean that you are happy that its not going to happen. Happy because its for the greater good. Happy because hopefully by missing out on this event it will be very beneficial for other people.

So you lose out on something that you really wanted but your feelings of sadness and upset are overruled by your feelings of hope and happiness that is for the better(for other people).

What is it called. What is the emotion? Compassion? I don't think so....

Help me out here. Find the word and win a prize!
