American editor and essayist William George Jordan said not to syndicate your sorrows. He viewed it as a grave disservice to others to share one’s complaints.
It is also a grave disservice to yourself. With the exception of catharsis done with a caring friend (and catharsis happens much less than supposed), voicing worries, complaints, resentments and injustices just fans in the inner fires of discontent.
Then it infects others with similar negative feelings.
Instead, try to simple alternative approach: think through the concerns. Is there an action that can be taken to address what is bothering you? If so, do it. Is there nothing you can do to make it better? Then let it go.
I know personally that is easier said than done. But syndicating one’s sorrows is easy to do and hard to live with.
