Only you can answer this question for it is a very personal thing. First off I want to say I am not trying to hijack you thread but you asked a question and I am sharng my experience with you which is a kind of exposure for me in it's self. This is a support group and we try to support each other in the forum here. If this upsets you please let me know. I am truly sorry and I a will not respond on your threads again. When I first started doing exposure work I took it in small doses. I would go to the mall and find a bench and sit there for say 20 minutes until the panic subsided some what. I used the breathing exercises they recommend on the site here. I also used a technique that I learned from Davit. If I became overwhelmed when out in a crowd I would take one object and zero in on it, like a tile on the floor or object sitting on a shelf. This would center me as a positive distraction. Then I would repeat the same exposure on another day and stay for longer each time. Now I can go to the mall if I want to I just choose not to. I have not read Dr. Weekes books so I can not comment on her methods. I have only used the CBT program and support group on the site here and it has helped me a lot. Ashley is one of the Educators on the site and she checks in about once a week. She may have some more specific answers for you.
I am not cured per say but my life is so much better the it used to be. I was even able to start taking a Quilting class a few years ago because of the support and program here and have been able to do things I never thought I would ever be able to do....Good luck to you...Red...
