Hi,
I also have CFS, Fibromyalgia and ME because I have autoimmune problems and I also find it difficult to tell whether my symptoms are part of my illness or my anxiety. When my symptoms are really severe I do tend to panic, but once I'm in a panicky state it's difficult to know if other symptoms are just fear or not.
I don't think I have health anxiety because my symptoms are real, but I do worry about those symptoms (if you know what I mean).
Just thought I'd let you know you are not alone.
Hope you feel better soon.
Love and hugs, shoegal xxx
