Could George Zimmerman Have Had A Psychosis Or Mental Episode?

George Zimmerman was very distrusting of authority-- he didn't even want to give his address out to help police--, he apparently is normally non racist, and he had prior problems, although he himself once stopped a crime in progress:

1. "In 2005, a woman filed a petition for an injunction against Zimmerman, claiming that he came to her house and became violent when she told him to leave, the Orlando Sentinel reports. Zimmerman, 21 at the time, filed a petition of his own in response. Just a month before that, the paper reports, Zimmerman was at a bar near the University of Central Florida when a friend was arrested on suspicion of serving minors. Zimmerman became profane and pushed a law enforcement agent who tried to escort him away. He was arrested after a short struggle. That arrest had been reported previously."
2. "Zimmerman, 28, was born in Virginia, aspired to be a law enforcement officer, and moved with his family to Florida about a decade ago. Though he appears not to have been an official member of the national Neighborhood Watch program, he was zealous -- perhaps over-zealous -- about patrolling his Sanford community, neighbors say.
   ""He once caught a thief and an arrest was made," Cynthia Wibker, secretary of the homeowners association in the gated community where Zimmerman lives, told the Miami Herald. "He helped solve a lot of crimes.""

Were Items 1a and 1b episodes of extreme anger and action thereupon which were related to extreme mental-function or emotional disorders? As for Item 2:

"Zimmerman...aspired to be a law enforcement officer...Though he appears not to have been an official member of the national Neighborhood Watch program, he was zealous -- perhaps over-zealous -- about patrolling his Sanford community, neighbors say."

He was also so paranoid about the type of professional which he wanted to be-- as I said, he didn't even want to give his address out to help police. And why was he out in the rain himself, by the way? A lot of questions are unanswered here. After all, for example, regarding Items 1a and 1b "injunctions have kept the cases' outcomes sealed"
