I've been reading a book called Missing Out: In Praise of the Unlived Life by Adam Phillips, who is a psychoanalyst. He talks about "frustration," and the way he describes makes a good parallel with dukkha:


"there are (at least) four kinds of frustration: the frustration of being deprived of something that has never existed; the frustration of being deprived of something one has never had (whether or not it exists); the frustration of being deprived of something one has had; and, finally, the frustration of being deprived of something one once had, but canít have again."
