Sorry I can't be of any help, but I've wanted to do DBT workbooks too. I've found one on Amazon that looks promising: https://www.amazon.com/Dialectical-B...dp/1572245131/

I might pick it up. I wonder if anyone else here has used that book before, as it seems pretty popular on Amazon.

There's a BP-specific one too, but apparently it's not that great.

I've been meaning to ask my T if we can do one-on-one DBT, but I always forget to bring it up.
