If you have access to therapy, there is a modality called EMDR. From personal experience, I strongly recommend it.

EMDR is traditionally used to treat PTSD. You play back memories in your brain with distracting bilateral stimulation and exercises that help reduce anxiety and panic. Over several sets the sympathetic response is dramatically reduced or eliminated.

Even if the underlying issue isn’t a “trauma” with a capital T, chronic anxiety has trauma-like qualities that still seem to respond to EMDR (at least in my experience).
