Sure hope you can find the right Dr sooner rather than later!!
One thing I've done in the past is look at
https://www.lupus.org and find the closest chapter to you. Then contact that local chapter and see what local doctors work with them. If they don't have that posted (usually an advisory board or something) then go to one or two of the local meetups and ask the folks you meet there. I've gotten better referrals that way than from my PCP.
Best wishes,
