Disappointment of sorts

I see a replay of a scene. I'm in it. And in it, I am upset, disappointed and also angry. Part of me wanted to blow up, the other wanted to weep. All these from having too much of an expectation of others. Perhaps I am naive. Perhaps I am too idealistic. Whatever it is, once again, I opened myself to being let down, among other things. I am being emotional about it because I do not want to deny how I feel about it. And it doesn't do anyone any good leaving it and not facing it.
I will not write at length about it. I just want to sleep on it and let it pass. Hopefully, when I wake up tomorrow, I will have got over it. And I will face the next week with it behind me.
