I went to a dbt group for several mos. I had a really hard time, because I am extremely shy. I found myself unable to share at all. There were several people with strong personalities who kind of took over the group. One woman in particular knew all the answers and kind of showed off her knowledge every meeting. It really bothered me how impressed T was with her, and how often T complimented her.

On the flip side however; the others in the group really enjoyed it and got a lot out of it. So it was just me and my personality that didn't tolerate it well. You may very well love it and enjoy it as others do.
