When you go to a ACON forum - it is mostly ranting.  People's needs to get things off their chests and out their head.  But in some respects in keeps you stuck.  It reinforces the injustices.  Part of that is validation and good that you're not in your torment alone and that the issues are real even though narcissists tend to deliver them in a stealth way.  It becomes a war cry.

By only getting input from other people in the same situation and in the same phase of recovery it perverts perspective.  It turns into a feeding frenzy.   Nothing feeds emotions like more emotions.

But part of it is bad because it keeps you stuck.   Getting to a place where you can acknowledge - it is an injustice and accepting it is a completely direction.

It might be good initially but I don't think healthy in the long run.
