DBT and CBT are two different types of treatment. DBT is specifically used to treat BPD (borderline personality disorder) while CBT is a treatment for depression. I started DBT therapy with my T in December. He is very excited about how this is going to help me. It is too soon for me to say what I think of it. There is a lot of online info such as dbtselfhelp.com to give you an idea of what it is like.
