The thing that worries me most about this situation, besides Roberta investing too much of her own energies into it, is that her friend will delay or avoid treatment rather than allow someone into her apartment. (I'm suspecting a
Collyer Brothers Condition rather than anything more sinister. Sorry, I saw the
The Dazzle, by Richard Greenberg not too long ago. )
We just had a slightly similar situation in our building. I and the fellow members of the board were advised that one apartment still had not had it's new intercom unit installed because the resident was refusing entry. This was interfering with the rest of the units in the line above her apartment from being able to use their intercoms to open the front door for deliveries.
At the suggestion of one of our members, we negotiated a half-measure. The resident erected two screens which blocked off any view of the apartment beyond the few feet needed to do the work on the intercom.
Perhaps the same could be done here. Your friend could devise a room inside the entranceway to her apartment, large enough to provide the nurse room to work but still providing her the privacy she needs.
