"Why deal with pros?"
They are much more sick than pros. Their power come from the others' weakness! Even when the others are not week, they seek for some "sweet spot" so they can drain you.
They can't mess with people "higher" than them, so they mess with the weaker ones!
Watch the movie "cruel intentions"!
"The narcissist has no significant or meaningful others in his life. They are often sad and malcontent. Their lives are a mess and often characterized by frequent losses (divorces, dismissals, failures, conflicts with authorities and the law, bankruptcies and so on).
The narcissist idealizes, then uses, then devalues, then discards. She is the epitome of the society of waste and consumerism - with other humans as the raw materials. The narcissist colonizes, then abandons. She's viral qualities."
They're absent minded sadists and they victimize everyone around them. Those in contact with them need guidance and help."
They were DEEPLY frustrated/alienated (no love) when childs, so they don't know what is it like to have empathy/love/affection! Narcissists HATE happiness and joy and ebullience and vivaciousness and, in short, life itself.
WALK AWAY from those people, they're very charming but it's just a mask, a facade.
"If some man were to say to your daughter: 'Here's the deal, sweetie. For several months or so, I'm going to pretend to be everything you ever wanted. I'll shower you with attention, affection and all manner of stuff to make you feel special. Then, once I know you're depending on me as your significant other, and have made a commitment, I'm going to quit pretending and be who I really am. I'm going to start treating you really badly, I'll say insensitive things, I'll lie, I'll cheat, I'll be really cruel, possibly humiliate you in public. Hey, I might even beat you. Your job will be to figure out what happened and do everything in your power to restore the relationship to what it was, until you either die, try to kill yourself, or collapse and get sent to hospital, which will be pretty funny because there's no chance whatsoever I'll ever pretend to be that 'nice guy' again - and by the way, it WAS a pretence. So what do you say, sweetie? Do we have a deal? Several years of hell in exchange for a few months of fantasy?'
