I don't have anxiety myself but Andrew Huberman (Neuro-scientist) says a good way to relieve anxiety is with breathing. Best to check him out. A very simple technique he calls 'the physiological sigh' = Breathe in, then breathe in some more, then exhale longer than the inhales. He says it's a direct control of anxiety. And it's free and always available! Check him on : hubermanlab.com or on youtube.
Good luck, Richard
