Unresolved conflict is really disconcerting to me, especially if there is no possible outlet to deal with it proactively. It makes me restless and I don't sleep or eat well. I feel physically sick to my stomach and I need to be physically distant for quite awhile to actually detach myself from it. I wonder how it works for other types. Perhaps it is an F thing. Or an NF thing. Or maybe just INFJ.
About the worst thing another person could do is to ignore verbal or written attempts to get enough information to shed light on the problem or to resolve it.
