You have put this very well. I appreciate it.

I'd like to add that:

* what manifests as rage or attack may not be so, often it is simply frustration or even a learned response triggered by internal fear produced by past experience. or inability to express what to that person is so clear but seems not understood by another

* mental dysfunction, depression, anxiety and such may be causes or contributors to such behaviour

* I note that "narcissism" is a tag and regret this for although I understand that such behaviour can be a symptom of narcissism, the behaviour you discuss is not proof of narcissism. In addition, narcissism is poorly understood by most and too freely its name attributed wrongly.

Having said that, I believe that your suggestions for dealing with it are very sound, perhaps in some cases, with the exception of seeking help from family or friends. I say this because these are often the very people who are often the least objective and who may not be as willing to assist as yourself but rather choose to judge. ☮️
