Hi FineW(H)ine welcome to our community. Clever screen name.
Is the ND you're seeing a lyme literate one? If not, I suggest you find one (or a LLMD} - for treatment.
You really want to get that heart rate/blood pressure issue under control if you can.
What you're describing would be so difficult to function.
Are you currently taking herbs for lyme...or is there some bart herbs as well?
How is your detoxing? You may need to step it up a notch...
