It seems that there IS a thought out therapeutic response to those feelings. My T uses it. Its written about in books.

I think there are several problems there though. Especially when it comes to.emotions there is a world of difference between knowing what you ought to do and being able to do.it. I have watched the mental/emotional effort my T puts into managing her self care.
The therapy profession seems to attract people with their own.issues and they may not have the training to control their feelings or with some people the insight to even recognize the damage they can do. Or are doing.
I don't know the answer to that issue because it seems beyond the scope of therapy consumers to be able to tell how well the therapist has dealt with their own stuff. We aren't psychic. I only know because my T has repeatedly shared "x is my problem and I need to.keep working on it". So it seems I'm sure to people who are traumatized by it like a sort of trap--you don't see that the therapist won't be able to deal with your feelings til its too late.
I think there are very good theories on how to deal with transference but therapists may not be able to execute them. Just like I know the theory of how to teach my horse certain gymnastic moves, but I lack the feel, skill and timing to execute the theory. It might be an issue of training, personal bias. Previous experience, whatever.
In that respect therapy seems a bit of a crap shoot. I have had two awful therapists and two amazing ones. The awful ones were both LSWs so I am prejudiced towards PhD psychologists as both my awesome ones has PhDs and a lot of advanced training.
I don't know the answer. But it does seem that the failure is not so much in the theory as in the actual humans executing it. Although Also feelings about transference and how to handle it seem very different based on the type of therapy the therapist does.
I think maybe some of the new review sites for consumer reviews might ate least begin to give clients a place to start
