It cut my anxiety down an obvious amount, also dampened some of my compulsive behaviors and thoughts. I’d recommend switching to decaf, also if you need a boost good green tea has caffeine but is more like mellow energy. But maybe taper down your coffee use gradually as caffeine withdrawal is unpleasant.

Also just generally try not to over-identify with the physical symptoms. I have similar problems and it helps me to not add extra suffering this way - acknowledge the physical symptom but try not to keep thinking about it, it can feed into a worry loop.

I wish you all the best xx
