Often it has to be a clinical diagnosis for lyme, and this often goes for the coinfections as well. Particular symptom make-up and how one responds to meds are generally guides to where to take treatment and what pathogens are involved. A lot of lyme literate doctors, when they know you have lyme will try to go for broad-based treatment to nail other potential coinfections. Lyme rarely rides alone, especially if the patient is quite sick it makes sense to suspect multiple pathogens are at play. It can be hard to say with pinpoint accuracy exactly which infections are involved, even some of the top llmds admit they sometimes struggle with this, therefore the broad-coverage strategy.
Babesia and bartonella are pretty common coinfections. I don't put much weight in a negative test, there are a lot of different species and strains of these pathogens, plus if the tests are antibody based that is also iffy because the infections are immuno-evasive/suppressive in nature, and some people don't mount much of an antibody response.
Do you get nightsweats or air hunger? those are pretty hallmark symptoms for babesia. Pressure headaches can be as well.
Bartonella often has psychiatric manifestation, anxiety, mood swings, manic feelings, etc. Of course each of these infections can have cross-over in causing various symptoms.
What are your main symptoms currently? I can't remember if you mentioned this, but are you going to be able to see an llmd? they would hopefully be able to point you in the right direction with treatments.
