I get the impression that at some point there was some sort of a social psychology experiment where the experimenters were trying to teach people to use this phrase whenever someone expresses the intention to suicide, or proposes suicide as a viable alternative to prolonging life. And the goal would be to see how often people are willing to parrot the phrase that doesn't even make sense as an argument against suicide.
One of the problems I have with therapy is that the clients don't exactly know if the therapist has what they want. If one hires a prostitute, it is more or less clear what each side wants and what they are willing to give in exchange. The only clear variable in therapy is what the client (C) is willing to give -- money. It's not clear if the therapist (T) has what the C wants, or if the T is willing to provide what the C wants. T is payed per session, not per successful healing or progress in whatever the C's goal is... OK, I feel like making a list.
T is payed per session, not for satisfying C's needs. ( T has a monetary interest to keep C in therapy.)
Vague variables, it's not clear what C's problem is, or what T is willing to do. (Vague terms.)
T is trained in psychology, and how to affect the minds of people. (How to manipulate people.)
C is looking for psychological help, and on this ground I'm assuming that C is psychologically vulnerable. (I'm assuming that C is vulnerable to manipulation.)
I put a few things together and see very favorable conditions for psychological abusers, sadists. Add to that the conflicts a suicidal person can have with a therapist and the fifth edition of psychiatry bible, and the parentalistic attitude of the mental health systems and some therapists, and you get something.
I would still go for therapy if I had the motivation, because I see both good and bad results as better than no results, but our payoffs may differ. Oh, and I wouldn't mention that I want to suicide or plan to suicide.
