Well, what did you expect?

That life would be fair?
That you would get what you deserve?
That the Earth cares about your preferences?

Frustration is the price we pay for unrealistic expectations.

We should instead expect for things to go wrong.
We should expect to be misunderstood by others.
We should expect that people die for all sorts of reasons.
We should expect for gravity not to cut us any slack just because we feel poorly.

The universe does not run on stories. It runs on laws. We can try to discover the laws but that is all.

The universe is staggeringly, mind-bogglingly big. Do we really expect it revolve around us?

Life is not a ♥♥♥♥♥. Life is. We can respond to it with more or less equanimity.

The sooner you drop your expectations of being the centre of the story, the sooner you will be happy. Just chuck 'em out. You don't need them. They aren't part of who you are. Liberate yourself from frustrating expectations and grow as a human.
