I find that my own mental anguish is most severe when I expect something good, but am forced to do without.

That is, I have no problem going without food, even for days on end, if I choose to do so. It's unpleasant at first but I get used to it.

However if I am looking forward to a good meal, but cannot obtain it, say because I don't have the money, or I am late to an event where the food was all eaten up before I arrived, then I am really, really upset about it - even though I only go without food for a few hours.
