I've had the most success with some of the aspects of DBT. For me, CBT was frustrating and not helpful at all.

You might bring this up with your current therapist and let them know that you feel you need some more concrete coping skills for dealing with daily panic, as well as skills for when anxiety turns in to a panic attack.

For me, mindfulness has been very helpful in averting panic if I feel it building, and in recovering from panic attacks more quickly.
