The narrator on the show and the doctors basically said that his mother needed to care for someone and he was it. Without him to take care of every day, she'd be lost.
I wonder if the mother has some sort of Munchausen (sp?) by proxy syndrome, or a cousin of it.
It has to be a mental condition in the enabler. No other way around it.
“Feeders,” as they are called, are into controlling their eaters. What better way to keep a person completely dependant and under control.
