I suspect that there would be a small team of therapists on staff whose job would be to monitor everyone and find whatever THEY need to keep going. Some might do yoga, others might do movies, etc.
But I would not expect that many of them required much attention. Remember that they were all carefully selected, highly trained, highly motivated, very busy, and doing exactly what they all new would help. A few might have minor problems, and maybe one or two would snap, but yes, they could give them some degree of therapy and/or medication and if necessary freeze them.
