One can learn about some of these things by simply facing the wall and meditating. Has been done for centuries. Costs nothing, no submerging oneself into an imposed hierarchy, no mind games at the hands of an inscrutable stranger wielding nebulous methods and theories whose motives are uncertain. This is not relational though, so has limits. But I know of no evidence that doing these things with a paid professional, whether psychodynamic or not, consistently makes people healthier or happier enough of the time to justify all the claims, the cost, the serious risks.

Seems to me an intimate relationship in the real world is far more likely to provide a reparative experience along the lines of secure attachment, given that it's (a) real and not contrived, and (b) the degree of investment is closer to proportional.

I don't see how one can have a secure attachment to a therapist. Seems an oxymoron. A needy or dependent client is likely to be deeply invested in the relationship after some period of time, whereas the therapist never will be. That asymmetry means the therapist values the relationship far less, and could drop it with relatively little pain. That sounds quite insecure.

Also if one does have a secure sort of attachment with a therapist, seems that implies dependency. Dependency on a parent is a good thing, but a paid stranger? I thought I had something secure, but my therapist saw it as dependency, and that became the basis for termination and severing of all contact. Result: my sense of sense, relationally, is worse than ever.
