I'd say herbs are only slightly better than medication in many situations, so I'm no help in that regard.
My advice would likely be similar to what you've already heard or read:
yoga, tai chi, light exercise, medication, taking time to do calming things that you enjoy, eat lots of potassium (bananas, sweet potatoes, tomatoes, peas, etc), no caffeine, reduce sodium intake, make sure you're getting enough sleep
Hope you feel better
