Perhaps this is like the stages of death that Kublar Ross talked about and people took to be definite and distinct stages that people move through rather than shifting from sometimes bargaining and sometimes raging and sometimes accepting (though I believe she later clarified she had not meant it the literal way people took it). Perhaps the stages are not, for everyone, clearly delineated and never to be revisited. Layers versus swirls.
Sometimes it seems more to me to be emperor's new clothes than others. Sometimes it seems more like religion in the way it is talked about (Faith for example being like therapy's "the process" which they all talk about but never define in anything but the most nebulous of ways). And so on. The thing for me that has changed is that I am not as frustrated constantly because I no longer give the therapist free rein. The thing that has not is I still do not understand what the woman is trying to do when I do let her speak. Some days I am more able to just ignore it and other days it still annoys me.
