Why do narcissists make everyone’s life around them miserable and traumatic, but he/she lives a happy and healthy life?

While the first half of your question is very true, the second part is not.

Yes… a pwNPD makes every single person miserable to the point that many find they need therapy after dealing with such a person. They put them through such misery, some are never the same…

Especially the people closest to them…family members, partners, co-workers, etc. But…do not think for one second these people are happy in any way. It may appear that way, but they are master manipulators. This is called a Mask and they get very good at portraying the part of a person who has it all together. But it’s far from it.

They live in a world of self loathing and despair and instead of trying to get to the root of the problem, they take it out on everyone else…all the while behaving as if they totally have their sh*t together. They don’t. And as far as healthy….how healthy could a person be who walks around with anger, jealousy and hate in their heart? Not just hate and contempt for everyone around them…hatred of themselves.

A hell for us…and hell for them. Where this is concerned…nobody wins in this scenario.
