Gee, Sunflower, you are really going through it--this is not the DBT I experienced at all. I went through two courses of it, too.....I guess like everything else, good leadership matters. All the proper information can be in place, but you need good therapists/doctors to head it up.

I am surprised, too, that the guy talked about your back--and that all you had to do basically was to "think good thoughts." How simplistic and naive can someone get! (I, too, suffer from spinal pain. I would have thought myself out of it a long time ago, if it were that easy.)

I'm glad to hear you're hanging in. Please don't give up on the DBT. If need be, then you might be able to find other practitioners (and surroundings) that are more professional and helpful.
