When the woman went on vacation I thought good I am saving money and when she returned I usually had an internal debate about whether to go to another appointment or not because therapy was not useful in helping me for what I hired one for at all. It was not un-useful for venting and grief when someone I deeply loved got very sick and died. But even then, the actual therapist did not matter - it was not the specific woman that was useful in and of herself.
I am not saying people shouldn't be attached to a therapist if they want, just that for me, I don't know how it would have occurred. I do get attached to those who I find are a real part of my life. For me, a therapist was never that - they were just a stranger I handed money to for rent). I am not passing judgment on others who find therapists attachable or who find it useful - I just don't understand it. For me, it would not have been useful.
To each their own said the old lady when she kissed the cow. (a favorite saying of my grandmother - a woman to whom I was very deeply attached).
I would think it all depends on what took someone to try therapy, what they wanted out of it, etc.
