Yоu аre cо-fаcilitаting a DBT skills training grоup. The group is midway through the emotion regulation module. One client, who has been relatively engaged in previous sessions, becomes visibly tense and tearful. She looks down at the handout, pushes it aside, and says: "I can't do this. Nothing works for me. I don't know why I keep coming." The other group members have noticed and the room has gone quiet. Using specific DBT distress tolerance skills and the dialectical framework, describe how you would respond in this moment. What would you validate, and what change-oriented message would you deliver simultaneously? How does the group context shape your intervention?
