gosh that is really bad - i'm quite surprised too and to be honest a bit disgusted at the provision - you would think they'd have lots of volunteers esp near a college!
I think if you and your therapist have made a decision then maybe it is the right one, prehaps there is a neighbour or friend that can support your mum? Or maybe get in contact with the social services - they usually provide help at times...or a local help the aged charity?

sending you my prayers.
