That's great that you've gone to a nutritionist and that you've had such positive results. I too went awhile back and he helped me to set up the program I am presently on.
I go to a private acupuncturist near me, I've been going regularly for 20+ years, I believe it is the single most important self help thing I've done for myself. She treats not only anxiety, but any issues I may have, carpal tunnel, tennis elbow, sciatica, neck issues, menopause issues, fatigue, etc. The basic premise is very different from Western Medicine which generally treats the symptoms. Acupuncture essentially keeps your body in balance so your own immune system is strengthened to fight whatever invades the body. It also keeps what they call the chi or life energy moving throughout the body so that there are no "stuck" places. The "stuck" places are what create discord, disease and disturbances in the body. I always feel relaxed, balanced, centered and peaceful when I leave. My HMO offers it but they only allow for a few visits per year and if I am in the throes of anxiety as a result of my daughter's shenanigans or some other health issues, then I want to go regularly. So, I found someone near me years ago who was highly recommended . You can google acupuncturist's near you and see what pops up.
It's a bit ironic, but my daughter's behaviors forced me to take much better care of myself. Little by little, as she went further off the rails, I kept increasing my self care. It was an eye opener to realize how far off track I'd become as I had made her the priority in my life. As I put the focus on myself, everything improved. Including my relationship with her. Oddly, I'm probably in the best shape of my life!!
