every mentally ill person you’ve ever worked with is basically lonely

Richard Rohr quote:
I once met a psychiatrist who said something to me that initially I thought was an overstatement: “Richard, at the end of your life, you’ll realize that every mentally ill person you’ve ever worked with is basically lonely.”
“Oh, come on, that’s a little glib, isn’t it?” I replied.
“Oh, I admit, there are surely physiological reasons for much mental illness, but loneliness might just be what activates it. Every case of nonphysiologically-based mental illness stems from a person who has been separated, cut off, living alone, and has forgotten how to relate in one way or another.” I still wonder if that might be true.
