I don’t know if I can add anything except to say exercise is an excellent suggestion from RT. Only one thing, be careful about the intensity, it’s been my experience when anxious that cardio can aggravate it sometimes, maybe it’s the adrenaline I don’t know.

Meditation sounds good, yoga, Pilates, swimming are all good in my experience- they focus your brain on the action and can calm thoughts . Focusing on the breathe is good too.
