n. Extreme psychological pain.
According to a study from Montpellier, France, "It has been suggested that psychological pain ('psychache') is a key factor in the suicidal process…We hypothesized that more intense psychache during a major depressive episode would be a factor of vulnerability to suicidal behavior."
Holden researches "psychache," or unbearable psychological pain, and how it relates to suicidal behaviour…"If they wish to address this sort of psychache then I think they need to focus in on which particular frustrated need is relevant for that particular individual," Holden said.
My neologisms are meant to clarify; to make sharper distinctions. (I see nothing frivolous in them.) Suicidology simply defines the field of knowledge of suicide and the practice of suicide prevention; psychache throws emphasis on the central role of psychological pain in suicide (and suicide's irreducible psychological character).
