Super big thank you for checking in @NikNik. I put the call out to you rather than the moderator because I was super anxious that a moderator who didn't know me well might inflame the situation. Karma didn't disappoint - but their response was SO off-kilter that it made me laugh - sort of like the psychiatrist saga. Let's face it, my life seems to be some sort of weird black comedy! 
I am about to head off to my GP to discuss the (A) situation yet again. I don't think this can continue...but I am at an utter loss as to how to either find someone else or try and go it alone. Given that absolutely everything I read about complex trauma says that it needs to be healed in the context of a safe relationship, I'm not really sure how to fix my brain by myself. 
It is very VERY hard to make sense of (A). She is a perfectly nice and caring human being, but as you said, the skill set just isn't there. And thus even though I firmly believe she WANTS to help, the cold hard truth is that she is doing harm.
It's like...she IS open to feedback and changing what she is doing, but in a weird way, it's almost like she is TOO open to feedback. That is, she doesn't have any sort of clear theoretical model or approach in her own brain. So she will DO whatever I ask...but it's like she is going through the motions without any clear rationale driving the behaviour. I super wish you could be invisible and sit in on a session @NikNik. I am TRYING to trust my own inside, but it's really hard not to wonder if the problem is me - you know, given that "Fred" always told me I was too f***ed up for anyone else to treat.
But then...I keep challenging that thought by reminding myself that I worked brilliantly with the uni counsellor, and I can also see that I could work brilliantly with @Former-Member, and most likely you to @NikNik if that was possible. So...I guess I do need to trust my own inside, and my own inside tells me that despite good intentions, (A) is doing just as much harm as "Fred".
Ok, well I'm off to the GP right now to talk through the muddle. Super big thank you for caring about me @NikNik.
