What is the best type of therapy for panic disorder w/agoraphopia and gad? I've been in therapy for several years.

Agoraphobia. Is a complex disorder. Cognitive behavioral techniques combined with some insight oriented psychotherapy have worked well for my clients. Progressive desensitization followed by exposure to situations that have caused anxiety help overcome the phobic situations. The insight oriented work can help uncover how the phobias developed in the 1st place.
Panic attacks. . Ssris are a good choice to start with. Discuss with your doctor.
