Mom lives in a double room and they keep bringing new roommates in every time somebody is waiting for a room to themselves.

So mom moved into this room a few months back and is now on her 3rd roommate that's only expected to be there for 2-3 weeks when she will get another roommate. Mom is starting to have issues from all the changing all the time, as soon as she gets used to someone they move that person out and the same day move another person in. It's disruptive. IS this normal for them to totally disregard my moms well being? She's lost almost 10 pounds and doesn't feel like she has her own place since this began in Jan. Can't they look for a permanent roommate for her and use another room as the revolving door of people coming in and out? I'm starting to feel like they're doing this intentionally. I realize others have a right to a bed, it just seems a bit much. My mom is normally the happiest person, never argues with the girls or screams and she's been a roller coaster of emotion not understanding why they're always moving everything around. What can I say or do if anything? Help please!!!
