It's really hard to articulate in a way that would make obvious sense. He was a very strict, classic blank slate analyst- zero self disclosure. Ie never so much as said he liked or appreciated anything about me, always called me by my second name, and I knew absolutely nothing about him. I was 'on the couch' for three years. Incredible 'archeological dig' for me, unearthing all kinds of suppressed childhood fears and also sexual reawakening. Deeply intimate and intense, and I am not a sharer normally! So massive leaps of allowing someone to see my inner self and reaching the point of feeling accepted and cared about, despite the lack of any explicit affirmation from him.
One day, after all that time, I guess he was unsettled/ pissed off/ maybe with me or with the world, and he suddenly self disclosed in a way that felt deeply rejecting. It wasn't this, but something like saying 'Oh, I wouldn't ever want to know you in real life'. I was totally blindsided- wasn't like I was attacking him or anything, so I still don't know what set him off. It landed in my regressed/injured parts as a total disowning, profound rejection from this 'reparative parental figure' etc.... which was a repetition of original trauma.... I also felt profoundly humiliated, having shared so much and exposed myself so much, to someone who apparently didn't even like me. (I think he did well enough, and was just in a defensive whirlwind of some kind, but emotionally that's how it landed) Then worse than this, he went back to being the classic analyst- not apologising, acknowledging that he'd broken his own rules or explaining where the hell that had come from. That felt gaslighting and cruel to me, and hypocritical- as he'd self disclosed in a moment of defensiveness- greatly hurting me, but wasn't willing to self disclose in order to help heal it. I struggled on for a few months with him, trying to feel better, but it was a major severing.... and I left in the end without any resolution or understanding.
After struggling to get over it on my own for some time, I went to a different kind of therapy (IFS), and that hugely helped to heal it in just four sessions. There were two major 'injured parts' (if you know about IFS) - a four year old, who felt shunned and disowned, and a teen girl, who felt she'd been stripped bare and humiliated. They are both much better now!
I think psychoanalysis can be immensely powerful - but for good and bad. Any model that is so reliant on the therapist getting it perfectly right is high risk. IFS, I prefer for this reason - it focuses on helping the patient build a better relationship with themselves... the therapist is the facilitator, but should not become the object of repair. (Ie they are not the reparative parent,,,, the patient finds their own inner core self/ reparative presence instead).
Anyway, hope all that makes sense and is useful.
