DBT is not for everyone, but I have done DBT and found it very helpful. The first DBT group I went to was just a bad fit for me, and I didn;t go back after the first time. But I tried another group, and it kickstarted the rest of my therapy. It can seem like some basic stuff, but there's something about going through it and learning and practicing it all as a group, and then with my T, that really helps me. It really helps me weather through the hardest parts of my PTSD a lot better than I would otherwise. For me, DBT helped the other therapy work I was doing be a lot more effective and useful. My T and I still work on it from time to time.
One great site about dbt is here: http://www.dbtselfhelp.com/
Here's another good (but older) thread about DBT from this forum (in addition to the link AG posted): http://psychcafe.ca/eve/forums...7331001#766007331001
Do you have any specific hesitations or questions or concerns? How are ya feeling about their suggestion?
Therapy can be one confusing journey at times - hang in there.
