The question changed from when I first responded.

I have not had the experience but I could certainly see how it would be uncomfortable shifting from individual therapy to group therapy with the same therapist!

While I can appreciate the post about clinics using group as a step down services for compassion fatigue, this is not true for all agencies. My agency uses group strictly for when the client requests it, as a step down service due to client no longer needing individual therapy (which is decided with client and therapist), or in conjunction to individual therapy. The transition into group should be discussed openly and honestly with your T about your thoughts and feelings, especially the feeling of discomfort about the shift.
