When I posted on this thread earlier, I forgot to add that I think that the OP would best be served if the T had been forthcoming about any kind of manipulative techniques being used. I suppose that increasing distress tolerance is a worthy goal, or finding out how/why one reacts as they do. I suppose it goes back to therapy being safe but not too safe.
If the patient ends up overcoming a problem or increasing his/her distress tolerance, all the better. I worry about T's being wiley because it might interfere with trust issues. Also, maybe it is me an my trust issues, but I have a hard time thinking of my T using a technique that causes me massive distress, to a point where it isn't therapeutical, and me not really being able to do anything about it at the time. I have difficulty with the Machiavellian tenet that the ends justify the means. I am not rigid on this concept, and I think it would be a good discussion, maybe in another thread.
SUM, I hope you are doing okay!!
