Except for yourself, no one will understand how much happiness or sadness you have had in your story, there is no empathy in this world, so don't be foolish to spread out your wounds and complain to others, there are many in this world

Except for yourself,

No one will understand how much joy or sadness there has been in your story.

There is no empathy in this world.

So don't be foolish to spread out your wounds and complain to others,

There are many salt sprinklers in this world,

And not a doctor.
