In case anyone is confused by your reference to me here. I did briefly post in response to @Estherbot, gently cautioning re doing nothing other than note the connection. I saw on the website his mention of CBT possibly relates mainly to secondary coping strategy support, which would be fine, though I was very pressed for time when I looked. But I also then saw he seems to recommend GET, at which point I deleted my comment. My gut feeling is to first consider if he might be more a bewitched disciple than out and out baddy. If that were the case then far better if he could become more enlightened; that might be a very optimistic long shot. But EC is a very bewitching influence I suspect, and I would be very surprised if a number of her followers weren't decent but misguided.
