I see how it could be an actual psychosis, but I read it as full of rhetorical questions / observations / figurative speech. For example "is sugar the enemy?" could easily be a commentary on having to choose between unhealthy calories and having not enough when offered free meal. Paranoia and purgatory is phrasing often used by people for more fancy descriptions rather than literal.

"It begun my psychosis" is a literal statement.

Maybe if you miss that sentence, the rest can fly under the radar. Assuming one also ignores the commonly reported correlation between homelessness and mental illness. But try and have those two elements front of mind, and re-read the article: it should be abundantly clear that this is in no way a healthy person down on his luck--this is a story of someone going through a mental break.
