I'd like to try to address the 'comfort' portion you mentioned above. (The other bolded portions are very important to understand, too!)
While in the hospital now, George isn't really responsible for anything at all other than following through on proscribed steps like attending counseling sessions and swallowing when his meds are provided to him.
He is guided when to eat, when to sleep, when to bathe, when he can have visitors, etc. Virtually all decisions are being made for him during this time, although he can speak up and add input. He doesn't have to do, be or hide anything under this type of care.
Patients are often relieved to be away from the normal little things in daily life; phones ringing, having to socialize with other people, caring for themselves or their home. And those are just the things that 'normal' patients are grateful to have respite from. Extrapolate that in George's case:
There is a comfort in that having had to keep certain things in control, be controlled by others around him, the media, on-going legal events, etc. The sheer peace that just comes from patients being able to pass the reins over to others for a while is part of the healing, and the therapy. I would imagine that is being felt many times more by GA now.
Taking steps to regain control of himself and his circumstances will be a long road ahead.
No wonder he is 'comfortable' right now.
