I might be preaching what you already know ? :You need to break it down to symptoms names that they understand. Lyme means nothing to them. Anxiety , depression, memory loss, arthritis , insomnia ect. Any Dr should be able to do that. Or did you try that route? I'm not from east coast , so cant help with Dr names.
I did this same thing in a different part of the country as plan B if I could no longer work. I changed jobs instead and maintained similar livable income.
