Not to be too preachy but...I do energy work. Meaning, I work hormones, neurotransmitters and other trace protein structures that cause us to feel what we feel. Anxiety is from too much ACTH, epi/norepi, etc. and not enough oxytocin, etc. Vasopressin has helped some people with PTSD. Here's a link to a NPR segment.
