I find both of these comments slightly disturbing. You seem to be expressing a separation between body and mind that is common in western circles to discuss but doesn't exist in my opinion within Chinese Medicine - or at all for that matter. From my understanding there isn't a body/mind, internal/external, there is just a system. While I agree that anxiety may be difficult to treat and you need to work on yourself and all of that, to say that this is independent of what acupuncture offers is, I believe, quite incorrect.
I look at the healing process as more of a cyclical event and acupuncture and herbal medicine and the other million things you can do as simply part of the process that enables healing to take place. Certainly anxiety is not simply biochemical nor is it simply caused by our spiritual, emotional and/or social issues. A change in one, enables a change in the other and there is a trust and a faith in this process. So you do some acupuncture and/or herbal medicine, you feel a little better, this changes your outlook and behavior, this in turn further lowers the notch on your anxiety levels, you do a little more acupuncture, more behavior change, lower again, etc. until things reach a more controlled state. Each process enables all of the subsequent changes to take place.
In some ways, you will surely remark, we are saying the same thing - but I don't think we are. What I am hearing from you (and I may be incorrect) is try this, then that, until you get something to work as if all of these things are mutually exclusive. What happens through proper treatment is this works itself out. In other words, more people need the changes that CM provides to help them feel calm enough to work on their thinking, on their levels of physical activity, their diet, etc. These changes in turn allow even acupuncture (and everything else) to have a stronger deeper effect. What I am hearing from both of you is that acupuncture and/or herbal medicine may or may not work and if it doesn't it is largely the patients fault (or their issues are somehow deeper than acupuncture can reach - which doesn't make sense either) and you should continue pursuing all other avenues until you find the magic bullet. I simply don't agree with this.
