What ever, those are just theories, and there is a clear deficiency with that diagnosing.. It would mean, that with several ANPs there will automatically be memory loss between parts, because in DID you need to have that. But that is not how it goes with real life systems. There are systems with many ANPs and no memory problems, and there can probably be systems with memory issues but just one ANP..
Rebellious systems have not read the books before forming.

I have plenty of experience of unfriendly people working in healthcare or social services. It seems sometimes to be the mood of some whole place, like you described. I have been hospitalized in two different wards, one open one and one closed one in the same hospital. The wards were like night and day, on other ward all the workers were friendly and caring, but in the closed side, even saying something to a nurse made them look at you like you should just leave them be and "do their work", which clearly wasn't helping patients.
