I really like guided meditations. There are some good free ones if you google "UCLA meditation". The ones with the singing bowls I find particularly calming. I never was into meditation, but once I really gave it a good try, I found it to be very helpful to calm my mind.
Other things that helped me: acupuncture, massage (even if you just get a partner or friend to do it), breathing techniques and stretching, recognizing the anxiety and talking about it, epsom salt baths, sun bathing, exercise, just facing the anxiety and saying I'm not going to let you control me
