Bear with me please when I say - just like Rebel8 - that warning bells have gone off for me as well.
Please don't understand my concern: I am happy you have found a counsellor who speaks "to" you about your need for healing and getting better. Can I ask though: Is the counsellor aligned with a Christian service? If so, it is clear that the counsellor is fulfilling the role of his religious beliefs.
However, if the counsellor is not aligned with any religious affiliation or church, I have to say I am uneasy about his approach. I also question the "judgement" of a counsellor declaring that the Witnesses are the most dangerous religion. Huh? What about the whacky religious groups that support violence against abortion clinics or scream hatred during funerals for military personnel killed in Iraq?
Talk about the so-called expert "going on and on" (as you yourself noted). What issues of his own are intruding in his opinion sharing??
I also get the impresion that once the counsellor "worked out" what he thought your "problem" was, he virtually took over. You were virtually his audience.
Any counsellor worth their training would know that people's religious beliefs often complicate matters. Parts of the person may not want to be "in" their religion, but other parts may be very ambivalent. It's a lot like sorting out one's feelings about a less than perfect relationship. The counsellor does not help by so quickly and robustly offering their well-intentioned opinions - which is all they are: Opinions. You could get that for free on the internet.
As for his going to the file cabinet and getting a typed up "heart-felt" religious invitation about how God loves you. I am sorry, but you were patronized and preached to.
Break the cycle: It is hardly progress to go from being patronized and preached to by the Witnesses to being patronized and preached to by your new counsellor.
