Depending on how far you are into your DBT journey you may find this workbook helpful. My therapist recommended it to me and I really enjoyed it but it is a pretty basic intro to DBT. Check out the preview before you purchase it to see if it would be helpful to you. I like to use it as a refresher now. https://www.amazon.com/dp/B07MMQ95VG/ref=dp-kindle-redirect?_encoding=UTF8&btkr=1
