Earlier quoted context omitted.
And yet there are actually suicide clusters, with people essentially "catching it" from their friends or loved ones who've committed suicide.
This seems like equivocation on the meaning of "catching it." Isolating yourself so that you either have no close relationships or somehow never hear about any suicides among your close relationships is a fairly nonsensical proposal, and probably wouldn't in fact decrease your chances of committing suicide.
