I'm also not sure what an intervention would mean in this context. When I went to ask my pdoc if I could see him for therapy, a friend of mine wrote a letter on my behalf, which he termed an intervention. I thought that's what the word meant, that a third party intervened between two other parties.

My previous therapist would tell me obvious things. I did not get much out of that therapy. No T I have seen (three so far including my current T) has ever told me what "everyone does". My current T in particular knows exactly how much I dislike that kind of phrasing, and I'm sure he would never say anything like that. (My best friend does, sometimes, and I find it very shaming when he does.)
