How about the chronic VICTIM? These unfortunate people can point a finger at someone or something to blame for every negative thing that has ever happened to them. In some cases they may be on target, but they can't move on and they just let it gnaw at their insides and waste a lot of energy being angry. At worst, they can't accept that sometimes negative things just happen and they cast about for a target to focus their frustration on. Anguish over "what could have been" eats at them constantly. This personality trait bogs people down and prevents them from moving on to more positive things. It can also be a tactic to avoid personal responsibility for the direction their life is going.
I think ex-JWs especially need to be on guard to avoid letting the WTS continue to bring them down even after they know it is a sham. The years invested in following a bogus religeous cult can never be reclaimed.
