I haven't heard of this type of therapy before, but checked it up online. I think it's worth giving it a try. I did do a very intensive group therapy program 8 hours / day 4 days a week for 3 months. It was lead by Psychiatrists, Social Workers and Psychologists. All aspects of my life were dissected. It was really hard, emotional etc., but it truly saved my life. My experience in any therapy, but especially group therapy is you get out what you put in. I was extremely nervous my first day, but it did get easier every time I went.

Good Luck and keep us posted.
