Yes, that's exactly what I'm saying about my mom, and how once the archaic (and IMO barbarous) treatments she was subjected to were discredited and she was brought under a more holistic kind of treatment (psychiatrist for meds, psychologist for talk therapy/art therapy, etc.) with a focus on reintegrating her with her family and being a more self-sufficient person she went from being a near-vegetable to an 'not quite normal, but within shouting distance of it' individual.
What I am trying (not necessarily eloquently) to say is that I have LOTS of experience with severe psychiatric disorders and why isolation is not (or has not been, in my experience) a good treatment for them.
Where are you getting the idea that Justina is isolated or in any way receiving improper care?
