Even having nothing to say is something to talk about. Not knowing what you want, but wanting motivation to do something is something to talk about. What are your thoughts about having nothing to say? What are your thoughts about what you might say, but don't. What are your thoughts about your therapist's response(s) to your having nothing to say, or response(s) to what you might say if you felt it was important enough to put words to?

Keep talking and explore what there is about having nothing to say.
