My doctor told me about Rhodiola Rosea, which is a Siberian herb that has been used to "help promote a healthy response to stress". There are many brands, I personally take the Gaia brand, it's concentrated liquid capsules.

My current therapist is helping me with EMDR (eye movement desensitization and reprocessing therapy).

My former therapist was working on Lifespan Integration and also showed me acupressure tapping points. If anyone is interested in learning the tapping points I can post them. It's just a lot to type

Five minute meditation helps calm down nerves. Close your eyes, focus only on your breathing and how it feels in your nose. If any other thoughts come to you, dismiss them. I like to be in a room where there's a clock ticking, too. My mind wanders constantly, and with the ticking in the background I have found I can concentrate better on my breathing.
