If that's what you mean by "healing from..." - moving forward, and dealing with current behavior without regard to the past, then yep, I agree.
I think MWD is overly enthusiastic in "Change Your Life..." about how easy it is to change deeply ingrained habits, but I do think SBT and behavioral type of therapy is the way to go.
I think shrinks and counselors do more damage rummaging around in the past and trying to force emotions and breakthroughs than they ever do any good.
I keep having images of Frazier and Niles Crane arguing over technique... or even better, Frazier and Lilith. Funny, I just watched an ep of that show. Hadn't seen it in years. :-/
