While not a counselor myself, I work in a hospital psychiatric program. I saw a long term therapist who worked in my community. We often discussed the state of the mental health system in our state. She self disclosed quite a bit over the years. We had some sessions that very little hard work happened because I needed a break. Usually this fallowed some intense sessions. We saw it as continuing to build our theraputic alliance.
