There's a place similar to 'college' but focused on adults. Admittance to that college is free. Anyone can attend. Room, board, meal plan. At least some classes must be attended; though the term 'class' is vague. For some a class might just be seeing a councilor to talk things over, or some other doctor prescribed treatment routine.
Some of the classes should be group activities that are cooperation based rather than rivalry based. The focus should be on establishing the expectation of positive interactions and experiences. Also about helping to train people to respond to others in the same way.
Suddenly, I think I'm describing kindergarten for adults from an amateur psychological perspective.
