That therapist I see does talk about how having her be there is supposed to be useful and how she is kind to the young me and some other stuff but I usually have checked out by that point. It totally creeps me out because I find the presence of the therapist is not reassuring and I would rather any young me be killed off. But she does bring it back up every so often. I understand the idea of not wanting to revisit a young self - particularly if one is viewing that as a vulnerable, moronic thing who, if only would have exhibited the slightest whiff of intelligence, could have warded off all sorts of things and done them correctly. Or that is how I see what the therapist describes.
MKAC - I think you find the presence of the therapist useful right? So it might be something to at least try. (But I also understand wanting to kill it).
