Thanks for bumping this, hurdity.
I had not noticed it before, but I have been so anxious the past few months - frozen into inactivity - that I spotted it straight away. It seems so simple and those who tried it say it works.
I have been trying those hypnosis tapes; it doesn't really matter what they are about, but they induce a relaxing trance for a while. I want to know more about mindfulness, so I will look into that. I've started praying the Rosary again (I realise that won't suit everyone) and I think that will help - I have been too wound up for it lately.
So yes, whatever techniques work to break the anxiety cycles.
