So, inquiring minds want to know...............

 .....................................is complaining cathartic?

The Oracle Google was consulted on the question, and this muddle popped up:

Though we think of complaining as an ongoing way of leaking negativity into our lives, sometimes it can have a cathartic effect. Often, what we need isn’t to ignore the “bad” feeling, but to validate it. Gilbertson argues that simply embracing how we feel can be a powerful practice. “ Emotions, once felt, will change themselves over time . . .

-----------------------------------

Complaining is terrible for your health, and the repetitive nature of it tends to hardwire you to perpetuate the behavior. (Neurons that fire together, wire together.) On the other hand, worrying and rumination activate the same part of the brain as creativity (the amygdala) and especially for those in creative fields, often seems like a necessary evil.

Taking a stab at it, my guess is that complaining can only be cathartic if said complaint is followed by action to either change the situation or to change oneself.  Your guess is as good as mine.
