I listen to Ben Greenfields podcast and he goes very in depth on lots of health related subjects with experts, and he had pn the author of Anxiety 101: The Holistic Approach to Managing Your Anxiety and Taking Your Life Back. Very interesting stuff, talks about a gene that makes you more susceptible to anxiety and have more negative responses to things than other people. There's a lot of tips and solutions in there and it really helps to understand the root causes of anxiety, backed up by science. 

Holistic does not mean crystals and hippie Buddhism, by the way. It's about understanding your biology and how to hack it to hack your brain - your body and brain are the same thing, not different entities. 

This is already helping me, hope it helps you
