My T has said before that I don't need to come in and share problems in my life every time. That sometimes therapy is about sharing the good parts of one's life, the successes, etc. The T can help you define further goals in your life, parts of yourself you want to develop, and will hear your progress on these things, etc. There can still be lots to talk about even if one is "doing well."

I hear some interesting contradiction in your post. On the one hand, you say you don't have much to say in therapy when you are "doing well." On the other hand, you also characterize these times as ones where you are dissociative and disconnected and in a "not so good place." How can you simultaneously be "doing well" and in a "not so good place." Interesting! Could this be worth exploring with your T?

Things to do when you have no problems to discuss:
--share the good times and successes and evidence of progress toward your goals
--share thoughts and reflections about a thought-provoking book you are reading
--share a dream
--share a poem you have written and what it means
--share a movie you saw recently and how it made you feel
--share a drawing/painting you have done and what it means

For example, there is this book I am reading how and it is bringing up a lot for me. I would like to share this with T.

My daughter's therapist does art therapy with her sometimes. They have had several ongoing projects they work on together in therapy. One was making a table and decorating it. Other times they build things together--fantastical lands of blocks and bridges and jewels and feathers and stones.
