Positive Tlab Lyme and Babesia treatment plan help

Hello. I have severe late stage Lyme disease and Babesia that’s left me with neurological issues and severe MCAS. After thinking I just developed MCAS and trying to treat that with only worsening conditions I tested positive for Lyme borrelia and Babesia. My LLMD just prescribed me azithromycin and atovaquone to start for three weeks as the first step. My MCAS is so bad at this point I react to everything even water so we can’t introduce herbs right now. I tried, horrible reaction. I know this is just the beginning and I’m nervous. I hope my doctor and I are on the right path. Any suggestions or encouragement is helpful.
