In the Catcher in the Rye, why should Holden be institutionalized?

I think that if one were to mount a case for Holden being
institutionalized, it would have to start with the fact that Holden is mentally
exhausted and not in the best frames of mind.  In looking at chapter 25, we see Holden
as being mentally driven to the edges of his own psyche in assessing and reassessing
situations.  He is not eating well nor is he physically feeling well, passing out in the
museum and being sick, overall.  There is a sense that he is free falling into an abyss
where he is unable to control what he is feeling and experiencing.  One could make the
argument that institutionalization is needed for him to feel as if he can gain some
level of control over his life.  A further argument could be advanced that Holden is in
need of psychological remedy, but in going to this point, one almost discounts much of
his own perceptions and understandings.  I am not willing to go there, as I think that
it moves into the realm of Holden being "different." Institutionalization is not the
answer for those who are simply "different."  Yet, I think that a case could be
plausibly made for him being institutionalization because of the mental exhausted
condition we see him at the end of the novel.
