Well I have pre my health conditions anxiety but I do feel when my health is in a bad spot and the pain is high I get this feeling you describe. I almost don't even know what to do with myself it is like I am running inside does that make sense? Are you on an anti anxiety meds? For me that has helped to a degree. It sounds like a good plan to check in with your doc. It is so hard to know what is part of our condition or seperate.
