It may not be a case of a diagnoses that is the source behind relationship issues. The diagnosis could be for the other person who has not sought help, so undiagnosed. It could also be a relationship with an antagonistic person, their personality style, a conflict of both people’s personality styles.

I have been obsessively trying to sort it out for myself as well (even have been diagnosed yet not sure if originated within me or the worst brought in me by the antagonistic person’s behavior).

I do find this site helpful and also enjoy knowing the different people here. I am very isolated, too.
