Interesting. I've only once in four years of therapy felt my therapist didn't have my best interest in mind (and I still wouldn't say aggression). But he usually (if not always) lets me know if he is frustrated or angry at me. Yep, he just goes and says it and brings himself really into the room like that. It's only now that i notice, this calm expression of anger makes it so that it is brought into both our awareness and he doesn't play mind games or attack me in subtle unconscious ways or anything. That hadn't occurred to me before.

My therapist is in therapy himself so I think that also helps keep himself in check. I can see a huge difference between him and other therapists who have never been in therapy themselves.
