No, she hasn't and it would seriously annoy me and make me question her trustworthiness if she did. I have no idea what this process that I hear being referred to is, let alone why a therapist would pressure a client to just blindly trust it because they said so. To me, that's stupid. I think it's what some therapists say to discourage clients from expressing doubts or questioning them. Why they feel the need to do this probably varies. Some probably just don't want to be bothered. Others are so insecure they can't tolerate anything they perceive as a threat to their authority. I think it is mostly just therapists not feeling like engaging with clients about something, so they tell them to "trust the process" instead.
