Heaven forbid that secular psychologists accept the fact that J.R.R. Tolkien was a very devout Catholic! That Smeagol forgot the taste of bread and the sound of trees is nothing short of Grace giving Sacraments that 1) keeps us sane and 2) reconciles us back into the fold should we fall to sin (and we do fall oh so often). But no no! Not that nasty elves' food! Let Smeagol diet on beer and vitamins from things that grow!
I recommend Lt Col Dave Grossman's explanations for those post traumatic stress disorders due to killing/murder. Maybe learning from subjects that dwell and die in combat will rigidly enforce reality into air-conditioned office dwelling doctors & psychologists. There's little time and margin for error for being wrong about questioning God's existence when your existence may very well end without a moment's notice.

P.S. Aren't psychologists still high on the suicide watch list? I heard it from "The Ninth Configuration".

Of course, they can always put out a press release saying there is a consensus, and peer reviewed articles passed around their group have supported the preponderance of evidence that shows no metaphysical evil affected Gollum--it was all due to poor diet and a misunderstanding of society.
