Judging by the posts I get the feeling that people don't know what a placebo is, so lets push the concept aside at least for one sentence.
You should allocate your hard earned free time into therapies that are proven to be better, like CBT and medication. (EFT is no better than a placebo, CBT and medication are better than placebos, therefore CBT and medication work better than EFT)
Logic 101. People with severe disorders have a weak placebo effect. EFT is no more effective than a placebo. Therefore, EFT have little effect on anxiety disorders on the severe end of the spectrum.
I mean, this isn't rocket science. If something is proven to be no better than taking a sugar pill, why not just take a sugar pill? You'll save time any money. (assuming the therapy isn't free) Unless you have the money to try every therapy, why not take the most effective therapy? You'll save money.
