I don't find your anxiety overwhelming at all. I want to help because I remember how freaked out I felt before I was finally diagnosed. Even though I was unhappy to find out I had Lyme (because by then I'd read enough to know what that means), it was still better than being sick with lots of weird symptoms and not knowing why. At least now I can do something about it. One other thing - I've been sick for years and have been diagnosed with lots of things and always I didn't completely accept the diagnosis because each one left out so many of my symptoms. I am at peace with this diagnosis because it is the only one that explains all of my health issues. What I'm saying is that I think most of us have a certain amount of awareness, at some level, of what is going on with our bodies. You're here because you suspect this is your diagnosis. I will be happy for you when you are able to confirm, or write off Lyme and/or coinfections as the source of your symptoms because then you can shift your focus to getting better.
I have Lyme; it doesn't have me.
