Group therapy is second-best to individual therapy. Group therapy is being recommended to you because your intake counselor believes that it is the best way to address your concerns. We do not put people into group therapy because we don't have space in individual therapy, or because we want to save time. We recommend group when it is the most effective method to help you. Your intake counselor can discuss with you why group is what we recommend for you.
Most people are anxious about being able to talk in group.
Almost without exception, within a few sessions people find that they do begin to talk in the group. Group members remember what it is like to be new to the group, so you will most likely get a lot of support for beginning to talk in the group. The group meeting times have been set by the group leaders, and you are asked to adhere to those times. Having a feeling and acting on it are two different actions. Acting out your feelings is not acceptable whether you act them out upon yourself or another member of the group.
