the "feeling cheated" part.
Feeling cheated is based upon one's own personal expectations of how their life should go and what they are entitled to. Life may have other overriding plans. So when you expected strawberries, and Life gave you brussel sprouts, you feel cheated. Life doesn't care . So maybe our only alternative is to become realistic or more flexible about our expectations? Or drop them altogether, and deal with whatever comes.
note: I expected Brussel sprouts, and got strawberries - this time.
