Doc knows “unequivocally” I don’t have Lyme bc I’m still in pain after 3 weeks on Doxy

Subject says it all. Gp was reluctant to give me doxy in the first place because I’m not a cdc positive. Reactive 39 igg, 39igm and 41 igg. Now he’s not going to treat me for Lyme anymore bc I’m still in a lot of pain 3 weeks into doxy. Pain is mostly nerve pain in back and arms. It rotates during the day and from day to day between like 4 specific patterns/ spots on back and arms and more rarely right leg by knee.

I don’t know how to convince my gp and now my bf (who is telling me doctors are the experts and they know more than me or people on the internet and I should blindly trust them to make me better) that i should still be getting treatment for Lyme.

I know my doctor is now going to waste more of my time sending me to useless specialists. Already saw useless allergist and rheumatologist who did and suggested absolutely nothing for me.

Help appreciated. What do you even say to these people to convince them?
