I haven't done legit DBT, but the T who taught me a bunch of DBT things and is trained in DBT is huuuge on validation. Almost excessively so. She would say that all feelings are valid even if not all feelings are justified. It has really changed how I interact with people and especially with my toddler. It's kind of magical.

Thanks for the podcast link zoiecat. I started listening to it, and it's really good so far.
